Type definitions for observables

[TrySound]

from in types accepts Observable which is not correct. It should be { [SymbolObservable]: Observable } according source code.
Flow has some problems with symbols. Don't know about typescript.

Sadly, I don't think it's possible in Flow right now to use symbols. That basically means that Flow users aren't doing to be able to use Observables in general, so I don't think we're currently making the situation any worse. If we are, though, and there's a way we could do better, I'm all for it.

@TylorS @Frikki: do either of you know if it's possible in TS?

In TypeScript the situation is similar. I've been following this thread for over a year now.

TypeScript is only capable of handling "well-known" (by TypeScript) Symbols in types. e.g. Symbol.iterator and other Symbol.**.

Thanks @TylorS. Seems like we've done all we can do for now until Flow and TS support Symbol.observable.

microsoft/TypeScript#5579 has been fixed.
