of people that #scheme has. While I think more people know *of*
Scheme and Lisp and understand the basics, my impression is that there
is a lot more people actively writing Haskell every day than there are
people actively writing Scheme every day.
However, I wouldn't recommend Haskell as an extension language for an
existing C-based application -- Haskell isn't designed for that role.
(cf. Lua was designed for *exactly* that role.)

aren't trying to get rid of it? How large is the guile user community
(people writing code and libraries in guile)? How active is the guile
developer community (people improving guile itself)?
My impression is that *nobody* likes Guile. At all. Over the years,
I've met *one* guile user who actively advocated it, and about twelve
months ago he learned CL and admitted that he liked that much better.

emacs22, emacs22-nox and emacs22-gtk are alternative front-ends, so
the smaller two can be ignored in the count. The emacs22-el package
is not used (since emacs22-common contains the byte-compiled
versions), so it can also be ignored. Arguably most of emacs22-common
should also be ignored, since it mostly constitutes applications that
are written on top of Emacs and aren't needed by Emacs itself. Even
if you count it, that's a total of (+ 412 4032 7548 51780) ==> 64MB,
not "100+ MB".
Comment withdrawn, the number was drawn from the last time I installed emacs, which was back when I used windows several years ago, and the emacs package for cygwin was 105mb and the native install was 120mb. Evidently it has been streamlined significantly in the meantime.
There's no real reason emacs22-common couldn't be split up into the
"core" files needed to run Emacs itself, plus a separate package for
applications. This isn't done because in general, nobody really cares
about wasting 50MB of disk space.
