The ideas here is to have nil act more like an empty set than an error catcher. So you get responses like

      nil.include?(:x) # => nil

instead of an error being raised.

WARNING! One should be aware that in some rare cases incompatabilites may arise when using these methods in conjuction with other libraries.
