A good exmaple is ObjectSpace:

  class << ObjectSpace
    include EnumerableArgs
    alias :each, :each_object
  end

  ObjectSpace.select(Class) { |c| c.name =~ /^S/ }

You can't do this with regular Enumerable b/c you cannot pass any
arguments through the enumerable methods to the underlying #each
method.

(Sorry if there are any bugs in the code. Ruby's not installed on my
system at the moment.)
