[go-nuts] concurrency pattern

Hi, I'm trying to improve a concurrency pattern, code here:

http://play.golang.org/p/WJBlS-x_Yt

Could I use buffered a channel to avoid returning nil (L33) ?
At the same time, I'd like to loop on ch instead of names (L38). Is
that possible?

I ran my example with -race and there was no race condition and it
doesn't deadlock (even when I force it to panic L26)

Any help is greatly appreciated.

Range over ch, then only put valid values on ch.

Thanks Dave.

Originally I did so, and got a deadlock, see:
