I'll take the opportunity to share with the community the code I have been actively sharing with you, Idle... It's slightly more of a heavy-built concept of doing it, and still heavily under development, but it adds another way of doing things:
*Note - The following code is an amalgamation demonstrating a small part of the project I'm working on. It contains only support for Windows operating system at the moment (the GTK/Linux support will be released with the first RC). Scroll to bottom to see how the construction of 'classes' and 'methods' are implemented.
