Given an iterator (for example from the ‘Interfaces’ doc). s = Squares(9) collect(s) # [1, 4, 9, 16, 25, 36, 49, 64, 81] Now given a StepRange R = 1:2:11 # 1, 3, 5, 7, 9, 11 how can I restrict the iteration over the Squares to the values of R to get the squares restricted to R: [1, 9, 25, 49…

How to restrict an iteration with StepRange?

Somewhat relatedly, check out RFC: jumping in iterators.

You can always do collect(s)[R]. It’s not optimal, but you don’t always need optimal
