polymorphically they are a collection with a first and last :)
No. (5 to: 4) is different than (3 to: 2) because they specify a different cursor position. Viewed as collection, they have no first nor last, they're just empty Nicolas

hi,
i am alone with this problem (or just mentally ill?), why every time i use #start and #end protocol for Interval, e.g.:
start := (1 to: 100) start. end := (1 to: 100) end.
why i expecting that something called 'interval' should answer its start and end (or begin & end, if you like)?
and i always hitting the wall with my head again and again.. because there's no such protocol and instead (after opening browser and looking at class, i figuring that i should use #first/#last, but it is completely unintuitive to me)..
So, i am alone with this? Or maybe intervals deserving to have start and end?
