Agreed. That way we could have utilities like these to check for all unary
operators. In fact, I don't see any reason why the same idea couldn't be
applied to binary operators. I would think that the usage would look
something like this:
Then you could do
where the latter expression is true if 't1 + t2' is well-formed, where 't1'
is an instance of 'T1 &' and 't2' is an instance of 'T2 &'.
Is this what you had in mind, or close to it?
