First thought: This sounds like an XY Problem. For any but a very small script, the torrent of parameter and return values from every subroutine call executed would be enormous and likely unusable. Typically, one is interested in the behavior of only a few critical subroutines. For this, print points or use of the Perl debugger (see perldebug and perldebtut) would usually be the tool of choice. Can you tell us more about why you want all call/return info?

Give a man a fish:  <%-{-{-{-<
