Basically I'm thinking of the the functionality used by SLIME here.. things like source-location (for M-.) and the who-calls introspection etc.

If someone has better wording for (i), please speak up.

Absolutely not :).

I think the better question is 'why take it further'? Personally, i don't use regexps that much, so i'm biased.. but...

Is the PERL regexp standard the one we'd like to follow? There is a perfectly good portable implementation that is an excellent candidate for inclusion in the 'standard library', so why would CLtL3 need to include its own description of a defacto standard from another language?

I'd personally much prefer a 'lispy' (read : verbose and understandable) implementation of regexps then the one from perl, and still wouldn't want it included as part of CLtL3.. regexps are not simple, and can be implemented without implementation support, so there is no good reason to include them in the base language.

Should we also include cl-awk? How about an infix macro? an SQL syntax library? A parser generator? why cl-ppcre over any of those?

Edi himself has spoken against the idea of 'standardising' on cl-ppcre (i can't find the reference right now), and IIRC his reasoning was similar to mine.

So, to turn the question around, how would including cl-ppcre help meet the goals of the project as outlined in the charter?

Again, i'll be your devil's advocate for the duration of these discussions, so please don't assume i'm dismissing this outright... but the questions and reasoning behind my arguments are valid... so i'd love to hear counter-arguments. Just to give you some ammo, ANSI included FORMAT and LOOP, and similar arguments could have been (and were) made against them.

Cheers,
