I believe it's at the other 'end for stick' of development process and
doesn't hurt 3.1 at all.

It could appear at the earliest in 3.2 or 3.3 in __future__... but I
think it doesn't mean we should freeze working on new ideas, even if
they have chance to be released not earlier that in three or five years.

But we already have 'with' in the language, doing completely different
things.

I propose 'using'.
