Okay, here’s my dilemma. It looks like this thread wants to devise
a new syntax for lambda, using e.g. (x, y) -> x+y, or the same
with =>. That’s great, but doesn’t open new vistas. OTOH, for
people using type annotations, a much more pressing issue is an
alternative for typing.Callable that is more readable, and
supports extra features that Callable doesn’t, like keyword args,
varargs, and pos-only.
FWIW, I *do not* want an alternate spelling for lambda.

If your time machine were still working, and you could go back to 1991
to change the spelling, yes I might like that. For that matter, if
someone had a good spelling for multi-line lambdas, I might like
that. Or *maybe* some other difference in behavior, but nothing comes
immediately to mind.

But allowing a few cryptic punctuation symbols to express an anonymous
function while still retaining "the name of a cryptic greek letter" to
do exactly the same thing seems like a strong non-goal.
+1.
That said, if I had to look at one, I'd like '->' much better than '=>'.
