[go-nuts] Single select case send and receive both?

Hello,

I had case when I wanted to receive msg and and send message from inchan to
outchan in for-select. What I have did is following.

for {
select {
case msg = <-inchan:
case <-exitc:
exit = true
}

if exit {
break
}

select {
case outchan <- msg:
case <-exitc:
exit = true
}

if exit {
break
}
}

Any better way of doing it? *If language supports* then what I want can be
done as following, if inchan is ready to send and outchan ready to receive
then only it succeed.

for {
select {
case outchan <- inchan:
case <-exitc:
exit = true
}

if exit {
break
}
}
