Actually, I would at first glance think, based on the parens, that: (1..10)-1 means ((1-1)..(10-1)) means (0..9) .... and if someone has been playing a lot with the superposition stuff, that is probably what they would indeed expect. That's also a valuable interpretation, since it means you can say things like (1..$n) * 10 And get a list (10,20,...) without having to change $n. However, by the same logic, @array * 10 means @array [*] 10 which it doesn't. So maybe the correct interpretation of the above is indeed this: (1..10)-1 # (1..10).length-1, e.g. 9 (oops!) (1..10) [-] 1 # (0..9) (correct, if that's WYM) meaning that (1..10)-1 almost always does The Wrong Thing(!) MikeL
