I really don't like that you can put an initializer statement inside
of the `!` parentheses. That can put a lot of distance between the
negation and the expression being negated. If `if!` is going to be a
thing, it shouldn't be able to be used with initializers. If you add
an initializer, just put the negation with the expression where it
belongs.

Similarly, I think `constexpr` should come before the `!`, not after.
