static property inheritance complaining when it shouldn't

I've seen that you've already closed many issues on this. But I'm reporting another one in hopes to wear you down ;)

It seems I can't change the signature of a static function in a derived class. The fact that the subclass is at all aware of the static functions on the super class is really strange.

I developed in C# for years, so I know what you were trying to do... but given that you don't support a new keyword like C# does, I think this behavior is really wrong. If you're looking to target being a superset of ES6/ES7, you need to correct this behavior ASAP. Generally in JavaScript, static properties are not copied to subclasses unless the copy is explicit.

I ran into this issue with RxJS Next, where I Subject must inherit from Observable, but they both need different static create() signatures. So I end up hacking around and fighting TypeScript.

Start by reviewing the issue discussion and the reported RxJS Next usage involving differing static create() signatures. Determine the intended static-property inheritance behavior and define a reproducible case; done requires an agreed type-checking outcome and regression coverage for that case.
