I've changed the flipflop operator/macro to "ff", short for "flipflop". This has several benefits. It's a doubled char like other short-circuit operators. It lets us add an "fff" to be equivalent to p5's scalar ... operator, and either of them can take the ^ modifiers to exclude endpoints. In trying to explain p5's flipflip operator, GrandFather on perlmonks just abbreviated it as "f/f", so it seems pretty natural that way. Also, upon a bit of psychological reflection, it's probably actually *good* for this operator to be an obscure one, because the very readability of "till" would tend to give people the false impression they know what's going on. Much better to send them to the manual to look up what "ff" means than to have them guessing wrong. (And being alphabetic it's easier to look up than a doubled punctuation character would be, if we had any punctuation characters to spare for a rare operator, which we don't.)
