Having a fixed binding could be useful elsewhere, for example, with

This question spawns from my ignorance: When would a functions
definition change? What is the difference between a dynamic function and
a fixed function?
All functions in Python can be replaced dynamically. While they're
running. From another thread. Really.
Implementing this is either inefficient, with a lookup for every
use (CPython) or really, really complicated, involving just-in-time
compilers, invalidation, recompilation, and a backup interpreter
for when things get ugly (PyPy).
