New keywords have a fairly high barrier to get over. Do you have a
convincing use case? I don't personally consider this particularly
convincing, not when it's pretty much equivalent to:
>>> import A
>>> foo = A.cool_namespace.foo
>>> foo()
To be honest I wouldn't even bother doing that, I'd just type
A.cool_namespace.foo() when I wanted it. Explicit is better than
implicit, after all.
