Finding out statically how many places a subroutine is called from would be an impossible task in perl. Think about routines called through object references with types that vary at runtime, eval blocks with variable substitutions, and new overloads that might be created at any time.

I think your best bet would be detailed runtime tracing using caller, perhaps hooked in with Devel::AutoProfiler
