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.

Commencez par le commit SlickGrid lié afin de reproduire l’accès global accidentel décrit dans l’issue. Consultez la discussion pour déterminer si le comportement demandé est un diagnostic du compilateur ou un nouveau flag ; aucun fichier source ni test n’est nommé, la réalisation nécessiterait donc une conception approuvée et une couverture correspondante du compilateur.
