Is there a way to use TypeScript to prevent accidental global access?

I just spent 2 hours tracking down this issue:

• We have a class with a prototype method called focus()
• Our code was calling focus(), but it should have been calling this.focus()
• The code compiled fine, because window.focus() shares the same signature as our focus() method

Is there a way to throw a compile time error when implicitly accessing global methods (on window, global, etc.)?

If not, a compiler flag would be extremely helpful. I would happily be more explicit about commonly used globals (window.setTimeout, window.document, ...) if it meant I could more easily catch insidious bugs like this one.

Comienza con el commit enlazado de SlickGrid para reproducir el acceso global accidental descrito en el issue. Revisa la discusión para determinar si el comportamiento solicitado es un diagnóstico del compilador o un nuevo flag; no se nombra ningún archivo fuente ni ninguna prueba, por lo que completar el trabajo requeriría un diseño acordado y la correspondiente cobertura del compilador.
