I do have some plans to come up with a specification / implementation of
first-class source-locations as part of my `editor-hints' project, where
vaguely something like this is included.


P.S.: I looked at FIND-SOURCE-LOCATION in swank-ecl.lisp; There's a
*tmp* global variable straying around, most likely used for debugging
purpose to get something to the REPL.

I think you have to do this this way, because ECL's swank-backend does
not implement the functions to evaluate an expression in the context of
a backtrace frame, or at least to get at the value of a stack variable.

Juan, is any of the above actually doable?
