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.
I personally would find it cool if 10 to: 1 counted down, it feels natural. But I must say I haven't thought it through. I do known that Interval is a class that leads to lots of discussions and disagreements.

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.
