I've been working on syntax lately, and based on that work, I think this goes
too far. It requires splitting the grammar in a way that needs greater parsing
power than LR(1), e.g. GLR. Unlikely to get by TC39 and implementors.
It would be better to preclude the ! and ~ prefixes from being used with the
{b} shorthand.
