My opinion for each proposed method. * `compact` - OK, I can imagine use-cases too * `product` - Negative; I concern about arguments (array or enumerable) * `flatten` - Negative; I concern about types of elements (array of enumerable) If you want `product` and `flatten` in `Enumerable`, submit separate issues to persuade me. Matz. ---------------------------------------- Feature #17312: New methods in Enumerable and Enumerator::Lazy: flatten, product, compact https://bugs.ruby-lang.org/issues/17312#change-88634 * Author: zverok (Victor Shepelev) * Status: Open * Priority: Normal ---------------------------------------- (The offspring of #16987, which was too vague/philosophical) I propose to add to `Enumerable` and `Enumerator::Lazy` the following methods: * `compact` * `product` * `flatten` All of them can be performed with a one-way enumerator. All of them make sense for situations other than "just an array". All of them can be used for processing large sequences, and therefore meaningful to add to `Lazy`. -- https://bugs.ruby-lang.org/ Unsubscribe:
