Assigning to function calls is orthogonal to reference types. For
example, Python manages assignment to subscripts without having
references just fine:
val = obj[index] # val = obj.__getitem__(index)
obj[index] = val # obj.__setitem__(index, val)
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 enough to say that
the syntax could exist, we also need to have semantics. What's the
use-case here? (That question is mostly aimed at the original poster.)
Python could use parenthesis instead of brackets for indexing and a
dictionary lookup. However it is too late to discuss this idea.
