OK, there is one more fix for the remaining minor regression.
https://github.com/D-Programming-Language/dmd/pull/713

The core issue to get imports right is that we add a lot of private symbols
to a module which in turn causes module interferences due to the access  
vs. visible behavior.
Christian got around that by not adding the symbols and handling them  
during symbol search instead.

If we shift to hiding protected symbols we can fix import AND protection.
It would also get rid of those incomprehensible symbol collisions and  
reduce module conflicts.
Some care is required with base class lookup and overloading.
Do you see any further issues with that approach?
