[ruby-core:111181] [Ruby master Feature#19177] optional offset for Array#index

[Dan0042 (Daniel DeLorme)]

Issue #19177 has been reported by Dan0042 (Daniel DeLorme).

----------------------------------------
Feature #19177: optional offset for Array#index
https://bugs.ruby-lang.org/issues/19177

* Author: Dan0042 (Daniel DeLorme)
* Status: Open
* Priority: Normal
----------------------------------------
String#index allows an optional offset:

```ruby
"the quick brown fox jumps over the lazy dog".index("the")   #=> 0
"the quick brown fox jumps over the lazy dog".index("the",1) #=> 31
```

I was a bit surprised that Array doesn't support this and I feel it would be a very natural addition:

```ruby
%w[the quick brown fox jumps over the lazy dog].index("the")   #=> 0
%w[the quick brown fox jumps over the lazy dog].index("the",1) #=> 6 instead of ArgumentError
```

[ruby-core:111207] [Ruby master Feature#19177] optional offset for Array#index

[byroot (Jean Boussier)]

Issue #19177 has been updated by byroot (Jean Boussier).

Status changed from Open to Closed

Closing as duplicate.

@Dan0042 can you revive the previous issue? The principle was accepted indeed, but it seems there was still a few open questions.

It's probably a bit late for 3.2, but would be worth trying to get this revived in January.
