If one were to implement currency conversion, how might that be done, in
general?
Does one need to store the conversion rates between any two currencies
(giving an N^2 size table), or might it be possible to convert any currency
to some universal currency, and from that again to any other, and
Actually, there is another advantage, which (I think) is at least as
important as the ones you cite. Namely, it is possible to define a built
in operator such that is_convertibleY,X returns false for
class X{};
class Y : X {};
and ambiguous conversion cases that (as far as I can tell)
I realize that I'm replying to a message that is now quite old. Hopefully
what I have to say is still relevant. Apologies if not.
Absolutely, there are a couple of procedural points I should make:
1) we are talking about a library only TR at present, core changes aren't
allowed just yet.
2)

not the other?
TryEnterCriticalSection is not portable. Specifically, it's not
available in the Win9x line.

John, what are the correct names? I think I can patch your Jamfile

that it seems a shame to leave users hanging.

So it sounds to me like the :blat is *not* part of the extension. It
sounds like the NT file name is made up of three parts: name, extension
and stream.
In which case I think it is fine to have functions extension() and

That completely scuttles the ODR, as far as I can tell.
Naturally, you wouldn't want to use a built in is_convertible this way.
Better to pass it as a template parameter directly, rather than wrapping
it: and_is_constT,

The problem I was trying to point out with is_const_or_int_convertible
was that if you want it to just work you really want some way of
grabbing context at the interface to any metafunction that might
need it, and passing it

Hi,
I have now uploaded a prototype of the Order programming language
interpreter to the files-section. Here is a link to the Order-folder:

Both the Order language and the prototype interpreter implementation still
have many many rough edges
