Feature #19177

optional offset for Array#index

Description

String#index allows an optional offset:

"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:

%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

Oops, sorry, duplicate of #17056, which has a PR and was accepted but... never merged?

Closing as duplicate.

@Dan0042 (Daniel DeLorme) 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.
