Of course it does, because you're looking up "std" and "std" is in both vector 
and map. Again, I am hornswoggled by my inability to explain how name lookup works.

Following the rules I listed:

import stl.vector;
import stl.map;

void main()
{
     vector!int v;
     map!(int,int) m;
}

compiles without error.
