[ALACPP] Re: Boost PP

[<arlo@xxxxxxxxx>]

Good point. I hadn't noticed that lack - I'm not really up on the later C
developments.

You could also make a higher-level library on top of boost's to strengthen its
capabilities with vararg macros. I'm sure that they'd like it, as long as it
either degrades nicely to pre-C99 preprocessors, or provides only optional
facilities and leaves boost PP unchanged.

I wonder if anyone's talking about this on their mailing list? I'm so far
behind that list that I've got no clue what they're up to, but an archive
search might be useful if you're interested in integrating your changes to
boost. You might also check out their developer's fileswap space, in the boost
yahoo group (don't remember the exact name, but you can probably find it from
their website).
