In general I'm in favor of expanding what can be done in guile because it
is pretty useful to have a highly capable api for manipulating a CAD
database.
Hear hear, Guile/scheme/lisp is jsut right for dealing with the lists of
attributes we have attached to drawing objects in PCB.

I'll just chime in with my $0.02 here. Then I'll slink away again.
IMO, it's nice to have multiple ways to number the refdeses.
Certainly, using guile to autonumber the refdeses in gschem is a "good
thing" (TM), and I support any enhancements to that tool, including
the two features which were suggested during the code sprint, i.e.:
1. Be able to clear all refdeses (e.g. C57 -> C?)
2. "Gently" renumber refdeses.
That being said, I also like -- and tend to personally use -- Dan's
refdes_renum tool. Here are some reasons to keep it alive, and
indeed continue to nurture it:
* More people feel comfortable hacking Perl than hacking guile &
binding it into gschem. Therefore, a Perl-based tool has a larger
support base. For example, John Luciani implemented feature #1 last
Saturday.
* I (personally) like having an external refdes tool, particularly if
it can do many more things than the gschem's built-in guile tool. I'd
probably end up using both, depending upon situation.
* Multiple tools performing one task fits well into the Linux way.
It allows for cross-pollination, friendly competition, borrowing
ideas, and so on. Therefore, there's room for refdes_renum, grenum,
and so on.
* As for file format changes, you do have a point, but I think the
risk that something will break REFDES=C? is low, and fixing the Perl
in case it does break is easy.
Finally, this thread started because Rikster wanted to hack
refdes_renum. Since C56 -> C? is done already, maybe he'll be
interested in implementing a --gentle option for refdes_renum? But
he'd better hurry, since I'm getting itchy to do it myself! :-)
