I'm out of town at a conference, and am not able to check this right
now, but I would suggest we proceed with caution here.  I use Allegro a
lot and I know that they have already hooked require into their
proprietary extensions.  I don't have any idea what would happen if we
were to jump in there.

I also don't know how portable the means are to inject ASDF into
require.  *MODULE-PROVIDER-FUNCTIONS* isn't ANSI CL, is it?

It's always bothered me a little to use REQUIRE and PROVIDE anyway, on
aesthetic grounds, since they are officially deprecated.
