We could provide operators for these, with a "reasonable" backpressure strategy for those that need it. WebCustom operator. As operators chains grow up, the chains must be split to make the code more readable. New operators are implemented as functions, and can be directly used in the pipe operator. When an operator is implemented as a composition of other operators, then the implementation is straightforward, thanks to the pipe function: how many calories in a pint of coors lager

WebRxPY is mostly a direct port of RxJS, but also borrows a bit from Rx.NET and RxJava in terms of threading and blocking operators.
