in thread coderef to an object method

In order to use a coderef as a method, you need to manually pass the object as the first arg.

Not necessarily.

#!/usr/bin/perl use strict; use warnings; use Test::More tests => 2; package Foo; sub new { bless {}, $_[0] } sub report { return [ @_ ] } package main; my $foo = Foo->new(); my $report = \&Foo::report; my $moreport = $foo->can( 'report' ); is_deeply( $foo->$report( 'abc' ), [ $foo, 'abc' ], 'coderef should work as method on object' ); is_deeply( $foo->$moreport( 'def' ), [ $foo, 'def' ], '... even if returned from can()' );

    Well, if you call a CODEREF (eg. as returned by ->can()) as object method without passing the objet itself as first argument, you'll lose the object context. So, you'll not be able to access the object properties, nor call any of these methods...
