Subject: Re: [Q] how to unflatten a flat-array

greeting James. what an intriguing way!

irb(main):001:0> arr = [ 1, 2, 3, 4, 5, 6]
=> [1, 2, 3, 4, 5, 6]
irb(main):011:0> arr << nil unless arr.size % 2 == 0
=> nil
irb(main):012:0> Hash[*arr].to_a.sort
=> [[1, 2], [3, 4], [5, 6]]

for me, as a beginner of ruby,
this is a fascinating black magic.
i will study hard to let it be white. :-)
