[ruby-core:100970] [Ruby master Feature#17312] New methods in Enumerable and Enumerator::Lazy: flatten, product, compact

Issue #17312 has been updated by matz (Yukihiro Matsumoto).


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`.
