Would Python be better with two subtly different assignment operators? The answer of "no" seems self evident to me.

Maybe this has been covered in the thread earlier--if so, I missed it, sorry.  But ISTM that Python already has multiple ways to perform an assignment.

All these statements assign to x:

x = y
for x in y:
with y as x:
except Exception as x:

And, if you want to get super pedantic:

import x
def x(): ...
class x: ...

I remain -1 on 572, but I'm not sure it can genuinely be said that Python only has one way to assign a value to a variable.
