closingNotifier calls through to subscribeToResult, so technically this could be ObservableInput<T>. That doesn't really make sense for the more finite values from Promise<T>, Iterable<T> or Array<T>. So I think the best option is to explicitly leave these as just Observable<T>.

I think this is related to #1246. Probably we want to support return values other than observable - but I'd like to take care it as separate changes set include type update / test cases to ensure its behavior if necessary.

Compare to previous type definitions having n-number of param (combinelatest, etcs) these kind of operators have single signature only. Is it necessarily required to export signature then import in coreoperators?

Sadly yes because we can't use typeof bufferCount, because bufferCount is a function that form of casting isn't supported.

OK, got point. Thanks for clarification.

One way to work around extra import is to use interface merging: export interface bufferCount. Now no extra import is required for BufferSignature, bufferCount acts as both function and signature. The benefit is marginal however.

Yes, I don't think this is serious issue need to be addressed. Mostly curious question.

Change looks good to me, (need to be rebased though) |
