question from Chris (slime dynamic variable...)

Please, note: I'm not sure whether or not this is what you are after: What
I got from your question is a way of checking out the coding, (though, me
myself use C-x C-e to eval the last sexp) there is a tool[1] in the
D.Touretzky's book called *dtrace.generic* Below the link & a sample of its
performing[2].
Hope it helps.
