This wouldn't work without additional changes to the import mechanism, since
the bindings of names are not used to resolve imports.  Let's not add any
more special cases.

The best way to avoid name collisions is to keep top-level names at an
absolute minimum by placing modules in a deep hierarchy.  Run-time overhead
may also be reduced this way, since many operating systems do a linear
search over all files in a directory when opening a file.  The best way to
support deep module hierarchies is to make relative imports as painless as
possible.
