-  # Encapsulates the common pattern of:
-  #
-  #   alias_method :foo_without_feature, :foo
-  #   alias_method :foo, :foo_with_feature
-  #
-  # With this, you simply do:
-  #
-  #   alias_method_chain :foo, :feature
-  #
-  # And both aliases are set up for you.
-  #
-  # Query and bang methods (foo?, foo!) keep the same punctuation:
-  #
-  #   alias_method_chain :foo?, :feature
-  #
-  # is equivalent to
-  #
-  #   alias_method :foo_without_feature?, :foo?
-  #   alias_method :foo?, :foo_with_feature?
-  #
-  # so you can safely chain foo, foo?, foo! and/or foo= with the same feature.
