Losing in what way exactly? Getting an error message in the minibuffer,
or getting to the wrong place?

I'm changing Slime so backends can provide even more information than
just local lexical variables.

For example, see


on how the backend for the ECL implementations reports locally bound
specials, and even restarts next to local lexical variables!

I'm saying this for the brave hero who tackles this problem so he knows
that the more information he can press out of a stack frame the better.
