Fixing this in my Emacs interface, I found that Hemlock doesn't use
the DEBUG-SOURCE-INFO slot when trying to find the definition of
something.  If you e.g. compile a defun in a file buffer in Hemlock
with C-x C-c, and the kill the buffer, M-x Edit Definition can't find
it.  I guess it is HI::FUN-DEFINED-FROM-PATHNAME that needs a patch.

Well, I have just been hacking at the ilisp package which originates
at CMU, so perhaps you'd better talk directly to Chris McConnell
(ccm@cs.cmu.edu).  I believe the interface to the old CMU Common Lisp
was made by Todd Kaufmann, whose email address I don't know - but
would like to know.

I do have some problems with the current interface, but they are
mostly silly technical things - the interface is basically great.
