Have we considered a name like `every`? (1..).every(2) # => 2, 4, 6, 8 I did not know that `step` could do this until I read this. The name does not clearly indicate that it would do that to me, but that may also be my lack of knowledge of it. `%` feels like moving in the opposite direction of clarity. It'd be great for terseness and golf but may be overkill for general usage. ---------------------------------------- Feature #14697: Introducing Range#% as an alias to Range#step https://bugs.ruby-lang.org/issues/14697#change-71577 * Author: mrkn (Kenta Murata) * Status: Open * Priority: Normal * Assignee: matz (Yukihiro Matsumoto) * Target version: ---------------------------------------- In #13904, `Enumerator::ArithmeticSequence` has been accepted for the representation of a range with step value. And in #12912, a new syntax of endless range `(1..)` has been accepted. Combining these new features, we can write an endless step range like `(1..).step(2)` in Ruby 2.6. It can be used for array slicing like python's `1::2`. If `Range#%` is introduced as an alias to `Range#step`, we can write a step range like `(1..)%2`. This notation is already introduced numo-narray. -- https://bugs.ruby-lang.org/ Unsubscribe:
