It would be interesting to see how common it is for strings which have their hash computed to be compared.
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.
I'm pretty sure it would result in a small slowdown.
Dictionary code has its own special path for string comparisons, so this is not an issue.
