how does one use a response channel that closes when some condition occurs to control coordination?

for instance, the onto-chan returns something that closes when it has finished putting things on the channel

how do I say "wait until you've put everything on the channel, then recur"

the idea is I want to put multiple collections into a channel one at a time

i’m also interested in the answer

hmm, actually. I see that apparently channels return nil when closed

so maybe you just do a blocking take?

hmm...

incidentally, that piece of information is tucked in the documentation for the close! function

@mfm yeah that seems to work
