Precisely. I don't see that there's a huge body of coders out there
just itching to use "Python but with some type information", or we'd
be seeing huge amounts of code, well, written in Python with type
information. They've been seen as an interesting curiosity, perhaps,
but not as "hey look, finally Python's massive problem is solved". So
I don't think there's much call for a *new language* on the basis that
it's "Python plus type information".

There's more call for "Python with C-like syntax", given the number of
times people complain about indentation. (There already is such a
language, but it's somewhat obscure, so it's quite likely Apple aren't
aware of its merits.) There might be call for "Python that can be
compiled efficiently to the such-and-such backend". But not "Python
with declared-type variables", not as a feature all of its own.
