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?

It was introduced at r52422 once, but removed soon at r52430 by a matz's objection.

And it's too confusing. ary&.[] and ary&.[]() for example.
