I believe deadalnix here meant something like this:

   import stl.vector;
   import mylib.vector;

   Vector a; // Ambiguous: could be from mylib or stl
   stl.Vector b; // Error: no such class stl.Vector
   stl.vector.Vector c; // Works, but requires extra typing

Which with working namespaces might allow case b to work.
