But (get|set|has)attr has been around much longer than enumerate.  I'm
almost certain they existed in 1.5, and perhaps as far back as 1.0.  If you
really want to compare the two, go back to your code baseline before
enumerate was added to Python (2.3?) and subtract from your counts all the
*attr calls that existed then and then compare the adjusted counts with
enumerate.

Given that you have more uses of zip/izip maybe we should be discussion
syntactic support for that instead. ;-)

    Mike> +1 on .[] notation and the idea in general.
