in reply to Functions to Methods
I can use functions to work with them. If I'd like to treat them like objects I've to change them into objects
First, you want to use an array as an object. You define an array class. Then you use the 'functional' interface again, which makes it ugly. Why not define a push method and call that?
Especially to handle the object as reference to the Array looks odd (of course it's nothing else than an blessed arrayref).
push @$obj, qw ( 12 19 35 37 48 98 25 );
The way you're doing it now is a bit halfhearted.
$obj->push(qw ( 12 19 35 37 48 98 25 ));
