BrowserUk has asked for the wisdom of the Perl Monks concerning the following question:
Is there any way to arrange for a callback to program level code as a running program crosses package boundaries?
I'd like to be able to have a subroutine in my module that gets called whenever the running program calls a function or method within the scope of that package, and perhaps another as it exits.
I can't even begin to see a way to do this, but then are are a lot of things in the Devel::* group of modules that do stuff with introspection that I wouldn't have thought possible had I not seen them in action.
