Divide a set by its element's class

require 'set'

s = Set.new([1, 2, 3, 'a', 'b', 'c', -1.0, -2.0, -3.0])
# Divide the set into the "String subset, the "Fixnum" subset, and the
# "Float" subset.
p s.divide { |x| x.class }

# => #<Set: {#<Set: {"a", "b", "c"}>,
# =>         #<Set: {1, 2, 3}>,
# =>         #<Set: {-1.0, -3.0, -2.0}>}>
