Nah, that was intentional. After all, this existed from before, and it's
very simple, :) so I need no credit for anything. Perhaps for the docs,
though (to come).

By the way, I see there are several suggested ways of defining these types,
such as char and struct { char[2] } used in "C++ Templates", as Dave B. Held
mentioned. It's the same for me what is used, as long as it works. :) Either
form will likely be the same for the compiler, as well. I think the form
used is quite nice and symmetric, though, but it may be changed, should
anyone want to:

typedef char (&yes_type)[1];
typedef char (&no_type)[2];
