Since

mod.foo(x);

doesn't work since mod is not defined.

we have to do

import mod : foo;
foo(x);

Why not

mod:foo(x)?

or

mod#foo(x)

or

mod foo(x)

or whatever

Reduces 50% of the lines and reduces the import symbol.

I realize that we could do

import m = mod;

m.foo(x);

but the idea is to only import the single function. I'm not sure 
if it matters. I thought importing single functions were suppose 
to be faster. Am I wrong?

The idea is to reduce having to litter the code with imports 
which I find I'm always having to do, or to make them global... 
just for a few calls in to them.

That is wrong. Importing is always done of the whole module.

All the `: func` thing does is limit the things introduced to the 
namespace.
