There is a construct specifically for this - mult/tap (create a mult of the source channel/s, tap the relevant ones onto a channel per listener). The pub/sub functions can also be used, if there is more complicated dispatching logic. Further, if the events aren't coming in streams (i.e. one event per channel), the most recent release of core.async includes a promise-chan function, which supports single write, multiple read. mult sounds like the right way to go, though. > And as for hooking up a single function to more than one channel, is that > where you'd use alts! ?
