Agreed, but only if this is implemented such that more deeply nested 
imports do not shadow less deeply nested imports.

I.e. if modules 'a' and 'b' both declare variables 'foo', then:

import a;

int fun(int foo){
     import b; // fine
     return foo; // fine, refers to parameter
}

auto gun(){
     import b;
     return foo; // error, could be a.foo or b.foo
}
