Typescript doesn't like to emit comments between the '()' and '{}' of a function.

Example:

SomeBinding() /* KeyBinding[T] */ {
  console.log("Bound!")
}

Emits this:

SomeBinding() {
  console.log("Bound!");
}

This is with 'removeComments' set to false in the tsconfig. This issue on the TS github implies they're aware of this but can't/won't do anything about it: microsoft/TypeScript#11046

However, the following is emitted as expected and could perhaps be used as an alternative syntax:

SomeBinding /* KeyBinding[T] */ () { ... }
