Look similar to http://d.puremagic.com/issues/show_bug.cgi?id=7373. In
that case I asked if renamed imports were supposed to resolve conflicts
and the answer was yes (and I agree) and the bug was fixed. I think it
would be best to be consistent with selective and renamed imports and
make them resolve conflicts. After all you are asking for a specific
symbol, I can't see why an implicitly imported symbol should conflict
with that when the intention is pretty clear.
