kingjamesid has asked for the wisdom of the Perl Monks concerning the following question:

Hello

my ($a, $b) = (2,3);
sub test{
($package, $filename, $line, $subr, $has_args, $wantarray ) = caller($
+a);
print $package, $filename, $line, $subr, $has_args, $wantarray ; 
}

If you just call `test()` you don't have two call frames, so `caller(2)` is rather meaningless. (Update: Actually you do have two call frames if you count the current, but since caller() starts counting at 0, you'd actually need 3 call frames) Perl 6 - links to (nearly) everything that is Perl 6.

And the OP doesn't actually call `test()`.	[reply] [d/l]
