$ ri partition

--------------------------------------------------- Enumerable#partition
     enum.partition {| obj | block }  => [ true_array, false_array ]
------------------------------------------------------------------------
     Returns two arrays, the first containing the elements of _enum_ for
     which the block evaluates to true, the second containing the rest.

        (1..6).partition {|i| (i&1).zero?}   #=> [[2, 4, 6], [1, 3, 5]]
