Devel::Caller - meatier versions of caller
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'
caller_cv gives you the coderef of the subroutine being invoked at the call frame indicated by the value of $level
Returns the arguments passed into the caller at level $level
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 returns true if the subroutine at $level was called as a method.
All of these routines are susceptible to the same limitations as caller as described in "caller" in perlfunc
The deparsing of the optree perfomed by called_with is fairly simple-minded and so a bit flaky.
