Why not just re-enter the same namespace in your test file then? What 
problem are you actually trying to solve here? If the problem is just 
package name prefix length, you can fix it with symbol rewriting without 
a ton of other complexity. I don't see a *need* for module inheritance 
or bulk imports or anything like that just to address the problem of 
symbol names being inconveniently long in source code.

It's a way of getting implementation inheritance. So is the module 
repackaging you're describing.
