Multiple monkeypatches should be fine, so long as each renames the
__call__ method to something unique.

I'm not convinced. Those small increments of performance really add up.
Look at how Python's performance over time has degraded as one after
another small bits of cruft accumulated.
It's also not just an if statement, it's a global lookup.

Sure, but after tinkering a bit, and compared to the original hack that
I did, this is sooo much cleaner. The amount of work required to
instrument a new object is close to zero.
