Pipe deliberately binds fairly low, so most other operators will happen first. Including +, ?? and
? :, for which there are tests:

So in the examples above, the second would add $x and $y first, then square-root the result. The
first, I think would probably need parens to avoid being invalid but I'd have to try it to be
