I like your ideas, and thanks for taking the time to write up a few lines 
of code. Looks like this will have to be a feature that i implement for 
myself. Heck, I had already planned on re-implementing the entire import 
mechanism anyway, because I like to spread my module source code across 
multiple files, and i want to explicitly define *HOW* those source files 
are combined to create namespaces at run-time, so that i can keep them 
separate, whist easily sharing state between them.. Python does not allow 
me to do this without resorting to "import contortions" and monkey patching 
-- but i know how to do it! *evil grin*
