I would even argue that the proxy solution is even *better*

In analogy with that, Python could implement what looks like assignment to
function call like this:
val = f(arg) # val = f.__call__(arg)
f(arg) = val # f.__setcall__(arg, val)
That's all very well, but what would it do? It's not

Do we really need this restriction? There do exist other languages without it.
What meaning would you give to "F(x) = 3", and why?

What?
I mean...what are you even talking about?
Assignmen
def F(x):
return x
x = 2
F(x) = 3
F(x) = 3
SyntaxError: can't assign to function call
Do we really need this restriction? There do exist other languages without it.
