Subject: [ruby-core:46381] [ruby-trunk - Feature #6727] Add Array#rest (with implementation)


Issue #6727 has been updated by duckinator (Nick Markwell).


And I just double-checked if those behave the same, and they do *not*:

Incorrect:

>> [].drop(1)
=> []


>> first, *rest = []
=> []
>> first
=> nil
>> rest
=> nil

Correct:

>> [][1..-1]
=> nil

>> [].rest
=> nil

So it would appear there are not other choices besides rest = arr[1..-1], at least not that fit on a single line.

I run into many instances where I end up using (({arr[1..-1]})), so I decided to add (({arr.rest})) to make that a bit less hideous.
