That's not true. The u"..." syntax is part of the language. from
future import unicode_literals is something completely different.

The Python language has no way of doing that - user (or library)
defined literals are not possible.

How? You've yet to prove that having a regex literal form is an
improvement over re.compile(r'put your regex here'). You've asserted
it, but that's a matter of opinion. We'd need evidence of real-life
code that was clearly improved by the existence of your proposed
construct.
