LGTM. I'd obviously prefer Babel used TS over Flow, as it's far more popular, but this PR should fix the issues I've found, at least.

Edit: Looking at CI, there's one instance where you put object instead of Object for the type declaration.

Oops, because I copied over from generators/typescript 🙈

Maybe this should be export declare function ${type}? They always start with an uppercase letter (thus are valid identifiers), and it would match https://github.com/babel/babel/blob/6467cd1e27ffe2a3a1cfe97bc8c67b407cb1e7c4/packages/babel-types/src/builders/generated/index.js

no. this is for the edge case of super() and import() where you can't export declare function super(): SuperNode;

but instead I made it:

declare function _super(): SuperNode;
declare export { _super as super };

to workaround of not being able to export super and import

@nicolo-ribaudo what do you think?

CircleCI failure is unrelated.
