Well, no, not exactly simple.

first, *rest = *input.enum_slice(3)
one, two, three = first.zip(*rest).map{|a| a.compact}

is the most elegant way i came up with - if you can live with a result like

["a", "d", "g"]
["b", "e", nil]
["c", "f", nil]

than you can strip it down to

first, *rest = *input.enum_slice(3)
one, two, three = first.zip(*rest)

which starts to look nice - if on the other hand you have nil values in your
data (and want to keep them) you are pretty screwed with this appoach.

cheers
