Yeah, this is an accepts-invalid for this test-case:

template Templ(alias T)
{
alias T!int Templ;
}

class C(T)
{
Templ!(C) foo;  // should be NG, must use Templ!(.C)
}

Templ!C foo;

void main()
{
C!int a;
}

This is because that class template is actually

template C(T) {
  class C {

  }
}

so the C inside is referring to the class C, not the template C. This code
works:

class C(T) {
  Templ!(.C) foo;
}

I don't know why uncomment the global instantiation makes the problem goes
away.

This issue can be worked around using:

alias C Workaround;
class C(T)
{
Templ!Workaround foo;
}

This shouldn't be needed though.
