But a with a buffer, offer does it when it can, or still returns false?

[cy]

offer returns true if it succeeded (an element has been transferred to a receiver or there was enough space in the buffer and the element has been copied to it) otherwise returns false immediately. send does suspend until an element get transferred to the buffer or to a receiver.
