IMO, ASDF should be augmented with (stable) hooks into REQUIRE for all 
capable lisps.  It should similarly try to handle all reasonable 
variations required by implementations.

Nikodemus, does this SBCL-contrib stuff refer to my email on sbcl-help? 
If so, I was wanting to fix ASDF to always hook into REQUIRE regardless of 
the SBCL_BUILDING_CONTRIB environment variable.  As it stands now, a (load 
"asdf.lisp") usually won't hook in; only a REQUIRE of the precompiled 
ASDF works.
