Hi Ben and Clement I have a collection (a dictionary in my case) and I want to get maximum 5 bindings out of it and iterate on them. I want keysAndValuesDo: or do: but only up to 5 elements.
aDict atMax: 5 do: [:each | ] So I learned from:to:do: aCollection atMax: 5 do: [:each | ] Does it make sense?
