Or directly, without using `exec`, feeding into the coproc a value which it
processes and returns to the initiator via the pipe:

    coproc {
        read -r incoming
        echo "I see you, $incoming"
    }

    echo Tony Stark >&"${COPROC[1]}"
    cat <&"${COPROC[0]}"


Outputs:

    I see you, Tony Stark
