mit welcher version?

Code (perl): (dl )

use strict;
use warnings;
use diagnostics;
my $m = bless{}, "main";
eval{ $m->foo };
if ($@) { say "perl $]: $@" }

ich bekomme:

Code: (dl )

perl 5.010001: Can't locate object method "foo" via package "main" at -e line 6.
perl 5.012004: Can't locate object method "foo" via package "main" at -e line 6.
