Indeed.  This is an important flaw, in my opinion, and (like
many others) i'm hoping it will be addressed in Python 3000.
It's listed as one of the things we hope to fix.

It amounts to more than just the convenience of creating lambdas,
for me -- it's really an issue of lexical scoping as a fundamental
property of the programming language, and has far-reaching (good)
implications.
