Yes, this adds allocation for Rx (the anonymous artifacts) but happens at declare/subscribe time. Once things are setup, calls go through the pre-"compiled" observer-chain / onNext channel 🚀

Thinking about this, it's not that you must have the same semantics. But just saying there's a reason for the extra "layers" of Rx that might not be that easy to optimize away 😅

This is really nice, but I think your impl have significant semantic differences to Rx.NET wrt hot vs cold observables. In Rx every observer has their own separate subscription chain while it seems to me that in your impl. they share the same upstream subscription? leecampbell.com/2010/08/19/r...
