The bug also causes a false negative of __traits(isSame), becuase isSame reuses
the same algorithm as template instantiation:
-------------------- test3.d
static assert( __traits(isSame, S.square, S.forward.square) );

struct S
{
    struct F
    {
        int  square(int  n) { return n*n; }
        real square(real n) { return n*n; }
    }
    F forward;

    alias forward this;
}
--------------------
% dmd -o- -c test3.d
test3.d(1): Error: static assert  (__traits(isSame,forward.square,square)) is
false
--------------------
