As a side question - Does the new Roles in perl6 cover the delegation-pattern ?

Yes, although not as extensively as Class::Delegation. You can see examples of it here. In addition Moose also supports Perl 6-ish style delgation like so:

package Tail; use Moose; sub wag { ... } package Dog; use Moose; has tail => ( is => 'ro', isa => 'Tail', default => sub { Tail->new }, handles => { 'wag_tail' => 'wag' } ); ## later in your code ... my $fido = Dog->new; $fido->wag_tail; # is equivalent too $fido->tail->wag;
Its seems to me that the main difference between Perl 6/Moose style delegation and Class::Delegation is the options for combining methods that Class::Delegation offers.

[Lady_Aleena]: This evening, I thought to myself, "I would love to search Netflix for 100 randomfilms from my database to see if they have them." So I went to CPAN to see if there were a modiule which could do such a thing. There is, but GUH! ...
[Lady_Aleena]: ... Does it have to be that hard and complex to use to do a search on Netflix?
Lady_Aleena grumbles.
[Lady_Aleena]: I really need to get back into the swing of Perl. I'm forgetting things from lack of use. I don't know how behind I am too.
