super method not present in type declarations

[jhpratt]

Bug Report

Current Behavior
Calling t.super() results in a compile-time type error, as super isn't present in type definitions. It does exist in the documentation and works as expected after compilation.

Expected behavior
The super method should be present in the type definitions.

Babel Configuration (.babelrc, package.json, cli command)
Not applicable.

Environment

• Babel version(s): v7.4.0
• Node/npm version: Node 12.0.0, npm 6.9.0
• OS: Ubuntu 19.04
• Monorepo: no
• How you are using Babel: CLI

As someone using TypeScript to minimize errors, the amount of casting is extremely verbose. By itself, that's not an issue, but coupled with errors in type definitions (this along with #10065) are forcing the use of unsafe casts and // @ts-ignore.

I'm not a TS expert, but how could we write this type definition so that it is valid code?

export function super() {}

[jhpratt]

@nicolo-ribaudo It's my understanding type definitions are auto-generated, so I'm not sure where the error is truly at.

A simple definition like declare function super(): Super; should suffice.

[nicolo-ribaudo]

No, super is a keyword.

I figured we can do

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