Argh -- I had missed that.  OK, then I don't like the proposal any
more -- having to switch order of x and y depending on what
parentheses you use would make the construct unusable IMHO, and,
without the generality of being able to use it in the integer
case, I don't think the usefulness is sufficient to warrant a
new operator.  Pity:-(.
