Okay,

So if I understand this correctly, even though the expr is called, and it's 
evaluating outside the scope of the website, will Python then eventually 
evaluate it *in* the scope of the website (through acquisition or inheritence 
or whatever?)

Sorry, I'm *so* not an OO programmer. ;-)

Wouldn't (or couldn't) there be a name-collision if I'm passing a variable/ 
constant that's already defined (or reserved)?

Thanks again for all your help!
