--- Comment #1 from RazvanN <razvan.nitu1305@gmail.com> ---
The problem is that the function has the const identifier which implicitly makes this const, while writeln expects a non-const argument. I think that this isn't an issue, but a programming mistake; removing const from the functions will solve the issue.

Simpler example with the same problem:

void main()
{
    import std.stdio;
    const Object o;
    writeln(o);
}

Not using const is a workaround, but a) writeln should be able to work with a const Object and b) even if it can't, it shouldn't cause a forward reference error.

I just tested that with DMD v2.081.2, both of the mentioned examples now compile and run without errors. This issue is thus fixed.
