You mean how to make it work in the existing C++ that has references?
Clearly you can't. In order to make a copy construtor or assignment operator,
you have to obey the prescribed forms which call for references.
This could have been designed around pointers instead.
E.g.
Object copy(&original);
and
copy = &original;
The copy constructor would look like:
Object *Object::Object(const Object *rhs)
{
// ... copy operations go here ...
return this; // not *this, blech!
}

No, I'd prefer the & operator to make a pointer. What you have *now* is
compiler magic.

And among those special cases is the handling of references.

Look in your /etc/inittab for a line that looks like...
ca::ctrlaltdel:/sbin/shutdown -t5 -rfn now
Remove this line, and you have disabled the <ctl><alt><del> keysequence.
Change the line to run a different program (say
ca::ctrlaltdel:/bin/echo 'somebody hit ctl-alt-del' >/dev/console
and you change the action the key sequence invokes
If you are concerned about luser escapes, you might also disable
the abort keys in your X server (see /etc/XF86Config for details)

On the other hand, writing a C++ interpreter is an experience I wouldn't
wish on my worst enemy. Just parsing the language for compilation is bad
enough, and working through the various issues with different compilation
units could turn into a nightmare.
I think your idea has a great deal of merit. GNU used to (still does?)
have a package called 'checker' which was intended to provide a runtime
environment for catching these kinds of errors at the point of infraction.
I'm not sure but there may have been a compiler switch which slightly
changed code generation to perform some of these basic checks inline.
The edit-compile-debug cycle could be shortened by using some form of
dynamic relinking, though keeping the lists of references that need to
be changed is a chore.
Another approach is to create a binary rewriting tool that inserts checks
for memory-use problems directly into an executable. Unfortunately, this
method is patented by the Purify folks.

Remember, NT is only POSIX LEVEL 1 compliant. This means that it
can handle standard K&R style c functions, and has some concept of
standard I/O. Even this isn't part of the standard package. To be
compliant, one must purchase the appropriate license AND the "NT
Resource Kit".
OpenVMS, OS/390, and QNX are also "POSIX level 1 compliant". For Level
1, you don't need to be able to fork(), you don't need to be able to do
pipe(), and you don't need to be able to do some of the other
interprocess capabilities.
OpenVMS is discouraged by knowlegable VMS administrators because of it's
performance hit. QNX has a "UNIX personality", similar to the BSD
"personality" of MACH. OS/390 has only recently been tuned to give
good performance without seriously impacting the MVS performance.
SCO did give Microsoft consent for POSIX level 1, and for TCP/IP.
Mainly because it was in the best interests of the investors (HP, IBM,
SUN, AT&T, Novell) to do so.

With all due respect, you wouldn't know a bug if it walked up
and invited you to join it for afternoon tea. RedHat 5.2 and
prior had HORRIBLE default security, RedHat 6.0 was far better.
I have installed BOTH versions on several computers including
a couple of ancient 486 machines, and in this they are FAR better
than OpenLinux, TurboLinux, LinuxPro and other "user friendly"
distros. In daily use with no crashes or significant bugs, I
might add. Fastest posting of updates of any of the distros I've
installed. Honestly, lots of positives, few negatives that can't
be easily remedied.
Doesn't make RH the best, doesn't mean there are no bugs. But
you have mistaken your lack of knowledge for a problem with the
OS, which it isn't. So to berate RH publicly when you clearly
need to get a clue isn't the best way to increase your knowledge
of Linux using Usenet. Have you ever considered using a search
engine?
Go to www.altavista.com, click on "Usenet", put the following into
the search:
+Oracle +Linux +"RedHat 6.0" +problem
and hit "search"... you'll get an answer to your install problem,
from comp.os.linux.setup no less! Now how hard was that? Took
me one minute (seriously).

RH has an *excellent* set of instructions on how to upgrade to the
2.2.x kernel from 2.0.36. I have used those instructions successfully
a dozen times, never seen the message you did. Did you even look on
their website? Sheesh.

I have to agree with a previous post, perhaps Windows 95/98 is for
you. But if you're going to stick with Linux, you won't like the
change that Slackware would represent -- requires MORE knowledge
of Linux at a lower level, and is BSD style init rather than System
5. That's not bad, it just means that it's different than what you
are used to from RedHat and most other distros. MANY people like
Slackware, but my bet is that you wouldn't. Your mileage may vary.

Oh my, such hostility! Maybe it would be best if you did go out
for tea with that bug, you need to relax a bit.
Look, no offense intended, but you clearly don't understand enough
about Linux to berate ANY distro. I don't have enough knowledge to
say categorically that one is horrible and another is so awesome;
the difference is that I realize this and use the Usenet newsgroups
to improve that knowledge rather than vent. We've all wasted too
much time responding to your rants, but we're all human and it's SO
annoying to ignore clueless pontification.
Probably mine included. <soapbox mode off> Best of luck in your
search for Linux enlightenment.

Maybe with respect to null pointers. But what about dangling references?
It's easy to create references to objects that no longer exist, because
their enclosing statement block has terminated or have been deleted.
This is yet another way in which references are as unsafe as pointers.

No, actually, what bothers people like me about the terminology (and
I've been using X since version 10 and coding in Xlib since X11R2) is
that user interaction usually comes to a server as moderated by a
client.
With X, user interaction comes to a client as moderated by a server.
This is truly a case where using existing terminology was not wise.
Perhaps it should have been "moderator" and "application" or even
"abstractor" and "consumer". Anything but client and server.
To give you a better idea of how bad this is, imagine that I walk into a
bank and speak to someone at the counter. I say "Hi, are you the next
available teller" and they say "No, I'm a security guard because I know
how to press this little red-button when a customer tries to steal from
us." This is an incorrect answer. You are acting as a teller from my
perspective, and should be willing to answer to that "class" name (not
to reference OO programming, which is a different bag of worms).
There are a number of mistakes in X's architechture and naming like
this, that I forgive because they're *still* the only ones that come
close to getting it right (you can't even initiate a remote Windows
session without horribly inefficient moderator software). Another
example would be the location of fonts. The font server was an attempt
to solve for this, but it was never truly adopted in full. Also, fonts
are not alone. What about a pixmap server? Try this one on for size:
"Caching proxy pixmap/font server". I want one bad! 1/2 ;-)
If X were to solve some of these basic problems; impliment alpha
channels and anti-aliasing in the server; call it X12 and be done with
it, I'd be in heaven. It'd also be the death of all of these me-too
X-replacement projects (e.g. the ill fated Berlin).
Sigh, back to my dream world... :-(
