It seems acceptable to allow it for the basic math operations most people are familiar with, but there is no reason why `||` and `^` should have a precedence relationship.

There are also some other cases where you might want to have precedence; for example, writing `x > 0 && x > 5` is fairly clear and useful. But in general, not everything should have a relative precedence with everything else.
