in reply to goto superclass method

Since we're all feeling dirty, you could also do what you want by temporarily faking the symbol table out so there is, for an instant, no child class method. Playing with Perl symbol tables will put hair on your chest, but you may also go blind.

use strict; package Super; sub new { return bless {}, shift; } sub dostuff { print "In Parent dostuff -- caller: ", join('|', caller()), "\n"; } package Child; our @ISA = qw(Super); sub dostuff { my $self = @_[0]; print "In Child dostuff -- caller: ", join('|', caller()), "\n"; local *SAVE = *Child::dostuff; undef *Child::dostuff; my $method = $self->SUPER::can('dostuff'); *Child::dostuff = *SAVE; goto(&$method); } package main; my $x = Child->new(); $x->dostuff(); $x->dostuff();
