Yes. Filenames and URLs are particularly problematic. Fortunately they tend to be O(100) in size, as opposed to O(1000) in size. Thus, the less demanding path of just hashing the characters is efficient enough for the cases I've seen so far.
IMO, we should not let Array hash ~= Interval hash coexist with Array = Interval Because it's like putting some traps on programmers path.
Yes, I agree. I'd vote on breaking #=, with the caveat that chances are some code will be broken. Does Pharo have a release strategy that allows more fundamental changes to go in, as opposed to maintenance/improvement fixes?
yes we talk then we summarize and describe a bug entry and Now I'm thinking that it would be good to have a page with important changes per version I would put there the discussions about the float changes we did in 1.0. Stef
