That's a valid stand point to take. I guess, at some point you just need to choose what your use cases are / what your audience is. You can get all the positions of c that differ from a, in Matlab: c(a!=c). In smalltalk, this could be something like: c at: (a differencesVectorWith: c).

Re: [Pharo-project] A more concise array access (using negative indices)

by StÃ©phane Ducasse

I agree :) > better than using negative indices. Not sure I like #from:toFromEnd: as the selector name, but I like the spirit of it, it makes it explicit. I'd probably like #copyFrom:fromEnd: better, but that's just personal preference as it goes better with #copyFrom:to: which would seem to be a related method in that protocol. me too. Now I could sacrifice that for polymorphism sake :) I think that polynorphic api are really cool and powerful. > I really don't want to learn 10 different ways to use #at:, I'd rather see 10 similarly named methods each doing it one way that look like they're all variations of a theme. When someone comes up with a new idea like #copyFrom:fromEnd:, it's easier to add that than it is to go back and patch #at: to do something new, it allows the system to grow over time yet remain stable for existing code.
