At which scope should this statement operate? Should it only be allowed at the
top of a module (like __future__ imports), or should it operate on a
per-function basis? Doing this for the whole process, as i think your usage of
the term "program" implies, sounds like a very bad idea to me.

Anyway, i think that this idea just doesn't "fit" Python, and "implicit none"
kind-of reminds me of the strict mode in Javascript. But other than in
Javascript, i don't think Python actually *needs* this. As said, linters cover
these problems for me.
