Those intermediate iterations could be dropped by composing the map functions together (same with the reduce), if that really was a performance bottleneck.

- moosingin3space 9y agoWith lazy iterators, there is the possibility of better composition of maps/filters/reduces. That's why I'm a fan of the lazy iterators approach -- otherwise the abstraction breaks too easily and it ends up looking like a for-loop anyway.
