Yes.  C++ does not allow you to define new operator symbols so I had to
pick one that already exists.  In fact I started with == but there is
not way to make the into a pair of similar-looking operators.

Yes, that's right.  It did not seem worth putting them into a loop.

Yes, though (as you note) it's not without its own problems.

This all started with Malcolm saying there no reason for the expression
to have a value, so I just threw out the possibility that it could have
a value that is of more use than simply returning one or other operand
(as an rvalue).
