  Similar to "auto ref" but no extra template instantiations

One question:
void test1(scope ref A a) {}

    test1(A(42)); // @safe, this temporary value is valid for mutation and "scope" ensures it does not leak scope
    A a = A(23); // no difference
    test1(a);

void test32(T)(scope ref T id) {}

    test32(1337); // Prohibited, no address for "1337"
    test32(a.id); // fine and @safe

Why test32 does not accept rvalue like test1? I think that "scope ref" should always behave same for rvalue argument - create temporary and take its address to "scope ref" parameter. Consistent behavior with any types is important for the generic programming.

Other than comment, looks good. Good work, Randy and Михаил!
