Python already has a syntax like this:

from __future__ import statictyping

Although I'm not sure how you'd go about implementing it plausibly.
It'd be a fairly backward-incompatible change; what would happen to
the modules you import? Either you would have to have a duplicate set
(one that uses statictyping and one that doesn't), or you'd have to
have statictyping somehow work on a per-module basis. As far as I
know, most of the other future statements are per-module (with the
possible exception of barry_as_FLUFL, which until today I was not
aware of).

Would static typing then apply only to module-level variables and
function-local variables, with the values in
lists/tuples/dicts/objects/etc/etc/etc still being dynamically typed?

I think it'd be easier to fork Python and give it a new name.
