This would be an enhancement request though, the spec doesn't say the symbols
are only visible by using 'ta' and 'tb'.

The issue name here is a misnomer, it's unrelated to base/derived classes.

So this would really be an enhancement request to make symbols in mixin
templates unavailable in the current scope when a mixin identifier is used:

mixin template T() { final void f() { } }
class A { mixin T ta; }
class B : A { mixin T tb; }

With the enhancement only A.ta.f() and B.tb.f() would be visible, A.f() and
B.f() would be invisible.
