[ruby-core:115322] [Ruby master Feature#14548] Allow some_array&.[1] to be a valid syntax

Issue #14548 has been updated by Eregon (Benoit Daloze).


What about using `dig` for this like `array_or_nil.dig(index)` and adding `class NilClass; def dig(*) = nil; end`?
There is also nothing wrong with `array_or_nil && array_or_nil[index]`.

IMO these `?.[` look too cryptic.

Feature #14548: Allow some_array&.[1] to be a valid syntax

----------------------------------------
Currently, Ruby allows accessing an array's index while testing whether the array is not nil with this syntax: `my_array&.[](1)`. I've always found this awkward but didn't mind about suggesting anything to improve this.

I was just reading about how JavaScript is probably going to support myArray?.[1] and found that it read good enough for me.

So I'd like to propose about the same syntax, replacing ?. with the Ruby equivalent &. instead. How does that look like to you?
