Description Andrej Mitrovic 2013-01-26 15:08:31 UTC 
Invalid code, accidentally reduced from Issue8785:

mixin template Mixin() { }

struct S
{
    template t1()
    {
        mixin Mixin t1;
    }
}

void main()
{
    S s1;
    s1.t1!();
}

2.060: 
$ dmd test.d
> test.d(7): Error: mixin test.S.t1().Mixin!() cannot resolve forward reference
> test.d(14): Error: expression has no value

2.061:
$ dmd test.d
> Stack overflow

Actually I don't know whether it's invalid, but the stack overflow was found by accident.

In the code, there is no forward reference. So, the error "cannot resolve forward reference" is not correct.
