Various HLLs need the ability to attach arbitrary handlers on subroutine/scope exit. (e.g. tcl's [trace])

Allison,

Can you suggest a path to resolving this ticket? Perhaps starting with: Which files a developer would have to look at to understand the problem?

Thank you very much.

We just need to come up with a name for this exit callback. entry also? profilers usually like entry callbacks also.
