I forgot about fall through in case statements!

But yeah, I was going to try to port rogue to Euphoria several years ago and I
got stumped on a part that used a goto. Basically it checked a condition and then
either started at the beginning of the game loop or jumped into the middle of it.
I couldn't figure out how to do it without writing a section of code twice.

Someone gave me the answer, it's here in the message archive somewhere.

I never did finish porting that program...
