Yes, the bearing is in the way that Perl compiles its code. Perl builds a name tree from the entire file before executing so it doesn't rely on the order of definition, Python seems to compile and execute code in a sequential manner and therefore relies on the sequence being right. I'm not sure if the undefined name errors come from the compilation or from the execution - does anyone else. I confess i've never looked deeply into how Python actually does its complile/execute cycle.
