I've done something like this before:

        sc, ec = [], []
        # => [[], []]

        ObjectSpace.each_object(Class) { |c| sc << c }
        # => 471
        require 'generator'
        # => true
        ObjectSpace.each_object(Class) { |c| ec << c }
        # => 473

        new_classes = ec - sc
        # => [SyncEnumerator, Generator]

See above (the argument to each_object).
