Expand description

Receive a value from a channel

Stack effect: ( Channel – value Bool )

Returns (value, true) on success, (0, false) on failure (closed channel). Errors are values, not crashes.

Multiple strands can receive from the same channel concurrently (MPMC). Each message is delivered to exactly one receiver (work-stealing semantics).

§Safety

Stack must have a Channel on top
