Provide a use case.

----------------------------------------
Feature #6596: New method `Array#indexes`
https://bugs.ruby-lang.org/issues/6596#change-86791

* Author: robin850 (Robin Dupret)
* Status: Assigned
* Priority: Normal
* Assignee: matz (Yukihiro Matsumoto)
----------------------------------------
I submitted a pull request on Github that provides a new method `Array#indexes`. It departs from `Array#index` in such a way that it returns an array of indexes and not the single first occurrence that is relevant.

The reason I want this method is that I don't understand why `Array#index` returns a single index if the parameter is in the array several times. 

Examples

```ruby
a = [1, 2, 3, 1]
a.indexes(1) #=> [0, 3]
a.index(1) # => 0
```

In my opinion, it's not logical to return only a single index since `1` is in the array twice.
