Re: [9fans] rc break

sure.  but that's a bit counterintutitive, isn't it?  the loop continues
looping without doing anything.  but i should talk,
i'm using c to count scheme-style. ☺

is break really that broken?  because of the lack of break,
you see some rc code that looks like it was written for a class with an
expansive no-goto edict. ;-)
