mixin template A( ) {
    template C( int n : 0 ) {
        int C = 0;
    }
}

mixin template B( ) {
    template C( int n : 1 ) {
        int C = 1;
    }
}

class Foo {
    mixin A!( );
    mixin B!( );
}

void main( ) {
    assert( Foo.C!0 == 0 );
}

foo.d(19): Error: __overloadset isn't a template

Or (without the wrapping class):

foo.d(17): Error: template instance C!(0) ambiguous template declaration
foo.B!().C(int n : 1) and foo.A!().C(int n : 0)

The two versions of C here introduced could clearly coexist and be referred to
as Foo.C!0 and Foo.C!1.
