Re^2: Require Carp - doesn't
in thread Require Carp - doesn't
This has nothing to do with Carp's dependencies (and it doesn't depend on warnings). In fact, your "fix" is actually incorrect and buggy and Steve Peters posted his comment to warn people away from doing that! It has nothing to do with dynamic loading either. It has everything to do with subroutine prototypes, as Steve explained.
Perl hasn't loaded Carp when it tries to compile the carp() calls. Without parentheses, it has no idea how many arguments the function should take (or even if carp is a function call at all), so it warns.
It would do that even if you weren't trying to use perlcc or Carp.
