Devel::Caller - meatier versions of "caller"

       Richard Clamp <richardc@unixbeard.net> with close reference to PadWalker by Robin Houston

       All of these routines are susceptible to the same limitations as "caller" as  described  in  "caller"  in
       perlfunc

       The deparsing of the optree performed by called_with is fairly simple-minded and so a bit flaky.

       •   As  a  version 2.0 of Devel::Caller we no longer maintain compatibility with versions of perl earlier
           than 5.8.2.  Older versions continue to be available from CPAN and backpan.

perl v5.40.0                                       2024-10-20                                 Devel::Caller(3pm)

       caller_cv($level)
           "caller_cv"  gives you the coderef of the subroutine being invoked at the call frame indicated by the
           value of $level

       caller_args($level)
           Returns the arguments passed into the caller at level $level

       caller_vars( $level, $names ) =item called_with($level, $names)
           "called_with" returns a list of references to the original arguments to the subroutine at $level.  if
           $names is true, the names of the variables will be returned instead

           constants are returned as "undef" in both cases

       called_as_method($level)
           "called_as_method" returns true if the subroutine at $level was called as a method.

       "caller" in perlfunc, PadWalker, Devel::Peek

        use Devel::Caller qw(caller_cv);
        $foo = sub { print "huzzah\n" if $foo == caller_cv(0) };
        $foo->();  # prints huzzah

        use Devel::Caller qw(called_with);
        sub foo { print called_with(0,1); }
        foo( my @foo ); # should print '@foo'
