Ok, here's a real ugly workaround:

extern(C) void printf(const char*, ...);
void h() { printf("h()"); }

class Bla
{
    mixin wrap!h;
}

private enum dummy {foo}

mixin template wrap(alias f)
{
    void blub(alias h = dummy)()
    {
        static if (is (h == enum))
            alias f g;
        else
            alias h g;

        g();
    }
}

void main()
{
    Bla b = new Bla();
    b.blub();
}
