AFAIK, CLISP doesn't record the source filename and the position in
the file of function or variable or definitions.  Without that
information we have to fall back to heuristics.  I think CLISP stores
the *load-pathname* of functions in the property list of the
corresponding symbol, but that's far from optimal.  It seems like the
*load-pathname* is only there to suppress some redefinition warnings,
not to implement something like M-.

CLISP should store the source locations of functions, macros, methods,
variables, defstructs, defclasses, and possibly user defined defining
macros in a easily accessible place.  The CLISP compiler could also
create a TAGS file, so that the information can be used without SLIME.
