It's treating it as ((-25) %) - (10), which is probably not so
surprising given the relative precedence of % and - ... though
I have to admit I'm not totally clear why it's not (-(25 %)) - (10)
instead.
We could maybe hack the precedence of the productions for prefix/postfix
%, but I wonder if it wouldn't be smarter to remove 'em altogether
(along with the two existing unary % operators).
