I want to consider here what it would mean to concretely implement the
abstract notion 'disallow rebinding of function names' and show what
would be behind calling the idea 'not feasible'.
Again, I'm more concerned about the function than about the name.
And the fact that "disallow rebinding of function names" is not feasible
in Python is a design choice, not an essential characteristic of every
programming language.
That's fine. My point was: you can't at the same time have full
dynamicity *and* procedural optimizations (like tail call opt).
Everybody should be clear about the trade-off.
Your wrong. Full dynamics is not in contradiction with tail call
optimisation. Scheme has already done it for years. You can rebind
names to other functions in scheme and scheme still has working
tail call optimisatiosn.
