Why the naked block instead of the infinite loop? Style thing, I guess. Over time, I usually end up hacking the naked block, adding and deleting conditions of restart and exit. The naked block has cleaner semantics for me, going up only when and where I tell it, and falling out otherwise. Certainly for this case I could have switched to an infinite loop once I saw that the form fits, but I don't know that when I first start, and I consider a naked block to be a more primitive form. {grin}
