Good morning monks!
I just ran into a "problem" with OO coding and I'm sure there's some elegant solution out there. So let's give it a try:

I got a Module Anything with a couple of methods. Now I want to have lists of Anything objects as Anything::List objects and I want to call the Anything methods on all objects in a Anything::List in a row.
That's easy of course but there are a lot of methods in Anything and all their Anything::List equivalents look exactly the same and thats actually bothering me!
And here is a snippet for demonstration: 
package Anything;
sub new {
    my $class = shift;
##  ... code here
    bless $self, $class;
}
sub prepare_create {
##  .. do something
}
sub create {
##  .. do something else
}
##  a.s.o. more methods here

package Anything::List;
sub new {
    my $class = shift;
    my @self = @_;
    bless \@self, $class;
}
sub add {
    my $self = shift;
    push @$self, @_;
}
sub list {
    my $self = shift;
    return @$self;
}
sub prepare_create {
    my $self = shift;
    foreach my $anything (@{$self}) {
        $anything->prepare_create(@_);
    }
}
sub create {
    my $self = shift;
    foreach my $anything (@{$self}) {
        $anything->create(@_);
    }
}
