Since all identifier-like strings mentioned in Python are interned, and 
therefore have had their hash computed, I would imagine comparing them 
to be fairly common. After all, strings are often used as makeshift 
enums in Python.

On the flip side, those strings are typically small, so a measurable 
overall speed improvement brought by such a change seems unlikely.
