So if we have the arrow shortcut for type hints, and an arrow shortcut
for lambda, then we can write code like this:
def func(arg:int->int=>x=>x+1)->int:
"I felt a great disturbance in the Force. As if millions of voices cried
out in terror, and were suddenly silenced."
I think that the likelihood of using an arrow for lambdas and type
hinting is a major point against this proposed arrow syntax.
And the arrow points the wrong way for an assignment! When we want to
show a name binding, we write:
name <- value
value -> name
we don't have name->value. Example:

I don't see any language that uses an arrow pointing from the name to
value for assignment:
