Design Edict #3: All destinations *must* be marked as such in the
bytecode metadata segment. (I am officially nervous about this, as I
can see a number of ways to subvert this for evil)

FWIW, I came up with purge because my first inclination was to spell
grep backwards: perg. :-)
I like purge, although except, exclude, and omit all have their
charms.
For partition function, I like divvy, carve, segment (in that order)
and almost anything other than separate, which IIRC is
As the last person to change the key hash algorithm, I'd like to chime in
here with a request that each PMC provide a string that the key hashing
algorithm can operate on. To some degree this is just selfish on my part --
I've got plans for upgrading the key hash algorithm in Perl 5 and Perl 6
But then sometimes you'd *want* hashing to be based on the
content.
OK, I'll bite -- when would you want this behavior? This behavior means
that once you change the contents, the hash value would become irretrievable
unless you restored the contents of the key. (Is this useful in functional

mix, and that's untenable.
I've improved (read: got working) 2 C++ string libraries in the past, both
with mutable strings. As performance was a primary consideration on both
systems that used these libraries, I chose to
I've no strong opinions on how it's done, but I do believe that
it's *very* important that subroutine calls be as fast as possible
(and significantly faster than perl5). This must be a priority.
To my mind that means that a subroutine should be responsible for
setting up whatever _it_
What is this talk of software 'releases'? Klingons do not
'release' software;
our software ESCAPES, leaving a bloody trail of designers and quality

No matter what else we do, we know we're going to be writing code for this

One C++ problem I just found out is memory management. It seems
that it's impossible to 'new' an object from an specified memory block.
So it's impossible to put free'd objects in memory pool and re-allocate
them next time.
It can't be done by the default new operator, but you can do it

Do something about microsoft's CRLF abomination.
I think for the case of Microsoft C++ used for the Win32 port, everyone
would be happy if Perl's sysopen, sysread, etc. did not require binmode.
Unfortunately, Microsoft made the decision very early on in its C/C++

Although Perl interpretation is divided into several passes (parser/lexer,
optimizer, tree/bytecode runner), all these passes are grouped together in
one binary. Under some memory-constrained conditions, it could be better if
each pass ran as its own program, passing the transformed data onto
