in thread Creating packages on the fly

I may be overlooking something, but how does that create packages that the code doesn't know about yet on the fly?

Maybe I need to be clearer:

Wx provides Wx::Window. Let's say that I'm going to use the namespace Jouke:: and my Wx::Window subclass would become Jouke::Wx::Window. I don't want to have a predefined list of classes I want to subclass under Jouke::, but whenever the main program calls Jouke::Wx::Window->new() it should be able to identify if Wx::Window->new can be called, and if so, subclass it as Jouke::Wx::Window, and add functionality to it.

The only part I'm having trouble with, is having a mechanism that catches every call to Jouke::Foo->whatever_method() without having to define Jouke::Foo in advance.

    you're right, Jouke::Foo->whatever_method() isn't covered in my example.

    Here is one that do:

    sub UNIVERSAL::AUTOLOAD { print STDERR "[[@_]]"; } package main; Jouke::Foo->whatever_method();
    outputs
    D:\TESTS\tperl>perl -w autocr.pl [[Jouke::Foo]]
