--- Comment #1 from Dennis <dkorpel at live.nl> ---
> It’s the only exception to this rule: Unary operators bind stronger than binary ones. (Another is the template instantiation operator, for which the exception makes sense.)

Implied here is that the exception for `^^` makes no sense, but you just showed
how it's consistent with mathematical convention, so it makes total sense to
me. Adding an error seems like needless code breakage and uglifying.
