Re: Getting a code ref to main

in reply to Getting a code ref to main

main_cv just returns Perl internal variable PL_main_cv which in turn serves special purposes.

As I see a situation, it is a very special *CV value that can not be deparsed (like can not be deparsed, say, sort internal function), and there should be special effort be made to make main_cv deparse-able, which, in turn, seems do-able to me, but not implemented nowadays.

    Well... ok. So then if main_cv isn't good enough is there a way to get a proper code reference to the main() subroutine or whatever the heck it's called?

    __SIG__
use B;
printf "You are here %08x\n", unpack "L!", unpack "P4", pack
  "L!", B::svref_2object(sub{})->OUTSIDE;
