$sorted = reduce { push @{ ^0 [ ^1 % 2 ] }, ^1; ^0 }, [[],[]], @numbers;
Hence: given an array of two arrays, put odd numbers (i.e. x % 2 == 1)
in the second array, and even numbers (i.e. x % 2 == 0) in the first one
(the zeroth array). Then return the new (filled out) pair of arrays for
the next number.
I like it.
