"enumerate" doesn't add complexity: it adds specificity.  When you use it,
there is no question of intent.  You are saying, explicitly, that you're
going to want to use the index.

Your way adds an enormous amount of complexity in that it's magic behavior
with no obviously good implementation.  What if the objects in my list
already have an attribute named "index" and I don't want your loop
contstruct to overwrite it?  What if I never use enumerate as it is and
don't want to pay for the extra overhead of modify every object I'll ever
get from an iterator?

Thanks, but no.  One of the things I love about Python is its lack of magic.
