If itâs always been that way - and things rely on it, sure. But it doesnât feel like the Smalltalk way to me. Having to know about adding -1 seems very C, whereas Smalltalk always seems more natural ... and 5 to: 1 seems like you would count down, not be an empty range and do nothing. But as you say, itâs personal. Iâm still curious though. Tim Sent from my iPhone

if you want to iterate down a series of numbers do you really have to do: 5 to: 1 by: -1 do: [â¦
I always assumed that if x > y the step was automatically -1 (but its not).
Expectations are obviously personal, but as far as I am concerned, I'd expect to see the behavior that Pharo implements. If you don't specify by:, you get a default value of 1. That's much simpler than a default value depending on the bounds of the interval.
