As an aside I think the non-null assertion operator should be transpiled via Babel from

`userId!`

to

`if (!userId) throw new Error('Non-Null Assertion Failed "userId!"')`

I like it, but I think it would violate the rule that TS code is simply erased. Though there are already a few exceptions like enums, but those are out of favor.
