10:23 PM Ruby Feature #20080: Introduce #bounds method on Range

Thanks for the feedback @matz! Is it the word `bounds` that you don't like in relation to the start and end values of a range? I personally think bounds or a boundary can be considered inclusive or exclusive which is why including `exclu... stuyam (Stuart Yamartino)

06:57 PM Ruby Feature #20080: Introduce #bounds method on Range

@Dan0042 great idea! At first I was against this because I thought it would make deconstruction harder but it actually wouldn't because deconstruction would work the same. I was thinking the second value if deconstructed would be an arra... stuyam (Stuart Yamartino)

05:55 PM Ruby Feature #20080: Introduce #bounds method on Range

@ufuk I like `#bounds` as a name also, great suggestion, let's try that. And thank you for showing beginless and endless examples, I agree with that usage.
@Dan0042 Sorry for the bad example, I didn't show a good use case I just showed ... stuyam (Stuart Yamartino)

04:26 PM Ruby Feature #20080 (Feedback): Introduce #bounds method on Range

Followup Reference: #20027
**Update 1/11/24:** (based on many wonderful suggestions!)
1. Call the method `#bounds`.
```ruby
first, last = (1..300).bounds # => [1, 300]
first, last = (300..1).bounds # => [300, 1]
first, last = ... stuyam (Stuart Yamartino)

Conversation moved to new issue for implementation of `#begin_and_end` method on Range: #20080 stuyam (Stuart Yamartino)

03:39 PM Ruby Feature #20027: Add Range Deconstruction

Yeah great point @Dan0042, `#minmax` _almost_ works, but as you point out it does not work because if the range is a reverse range you get `nil` for both values. Interesting!
```ruby
(1..42).minmax #=> [1, 42]
(42..1).minmax #=> [nil, ni... stuyam (Stuart Yamartino)

08:47 PM Ruby Feature #20027: Add Range Deconstruction

Thanks for the thoughtful responses @shan and @mame!
Shan, you make great points. With the next `it` syntax coming in ruby 3.3 you could also do:
```ruby
low, high = (42..420).then { [it.begin, it.end] }
```
Mame, thank you for discuss... stuyam (Stuart Yamartino)
