Hi I was looking at how we can turn a collection into a stream. I played with g := Generator on: [ :gen | | current | current := 0. [ gen yield: (current := current + 1) ] repeat ]. g next. and now imagine that we have (1 to: 1000) collect: [:each | {each -1 . each . each + 1}]. I was wondering how we could turn it into a stream (1 to: 1000) asStream collect: [:each | {each -1 . each . each + 1}]. and what would be the asStream method. for index based I can see that next next is something like next ^ self at: (current := current + 1) and collect: could be rewritten to use a generator. Now does anybody play with this already? Does xtream provide a way to do something in the same vein? We can have a stream of blocks. Stef
