Mr Business, you are approaching it from the wrong side.

Chunk is not about variables or much about control structures. It's about building networks / circuits of signals, and controlling time.

The two main aspects of chuck are:
- The chuck operator connects sources, sinks and filters of signals of varying types.
- It let you write temporal events in a straightforward way. It's more straightforward because the loop that is inherent in all realtime/audio producing network is completely abstracted out.

The public of chuck is people who got fed up fidling with MAX/MSP, which presents those network of signals in a more blatant way: graphically.

People using chuck are the same sort of people who are into Live coding

Slub for instance uses (or at least at the time used) Perl to do live coding / music performances. (see http://www.perl.com/pub/a/2004/08/31/livecode.html)

A group on this topic was formed, called TOPLAP. (http://toplap.org/index.php/Main_Page)
