fix: propagate bound task exceptions in iterate#5
Merged
Conversation
Match Julia's Channel behavior: when iterating over a closed channel, check for stored exceptions from bound tasks and throw them instead of silently returning nothing. Previously, if a bound task failed with an exception, iterate() would catch the InvalidStateException from take!() and return nothing, swallowing the original exception. Now we check ch.excp and propagate the stored exception if present. This ensures errors in producer tasks properly surface to consumers iterating over the channel.
