Indeed it is an X/Y problem.

I'm thinking about recording runs of a large legacy codebase - before and after making changes to it - as an aid to writing tests- which don't exist for this codebase. A record of which subs are actually being called, with which arguments & return values, is a good starting place showing what's in use = a starting place showing what to test.
