setImmediate should probably be replaced with setTimeout(0,

Appears not to be supported by any current browser, and all the code I've seen that needs immediate microtasks uses setTimeout with a 0 timeout argument.

(yes, this could have been a PR, but researching and confirming I'm not woefully confused here seems like it's going to be most of the effort and since I'm not 100% sure I'm right I can't really PR that part, sorry)

That's a fair suggestion. Can you show me the use case for observable-to-async-generator in a browser environment? I guess, it's going to be related to an Angular app, right?

Originally, observable-to-async-generator is designed for use in NodeJS environment, where setImmediate is supported. But if removing a reference to setImmediate is the only thing that stands in the way of supporting browsers, I'm all for it.
