No, there's more than that. When the coroutine does a print, it stops. When
the main code does a read from the filehandle, it stops and the coroutine
picks back up. (Well, more or less)
It's a simple form of threading, sort of. Perl's actually in both the
coroutine and the main code at the same time.
