This issue closed without implementing
Would be nice to have multicast of Iterable/AsyncIterable via fork fn for independent parallel consuming
Like RxJS share, that multicast Observable

Thank you for your interest :)

We've only dealt with unicast so far.
Looking at rxjs, it seems like multicast could also be useful.

Is there an expression you're thinking of?

ex)

const add1 = pipe(
  [1,2,3,4],
  map(a => a+1),
)

const forkedAdd1 = fork(add1);
const forkedAdd2 = fork(add1);

forkedAdd1.next(); // 2
forkedAdd1.next(); // 3
forkedAdd2.next(); // 2
forkedAdd3.next(); // 3

Yep, for allowance of stream multicasting to independent substreams

Thank you for the good reference!
I'm busy with work right now, so it might take some time before I add it🙏
