-class Hash
-  private
-    # Returns a JSON string representing the hash.
-    #
-    # Without any +options+, the returned JSON string will include all
-    # the hash keys. For example:
-    #
-    #   { :name => "Konata Izumi", 'age' => 16, 1 => 2 }.to_json
-    #   # => {"name": "Konata Izumi", "1": 2, "age": 16}
-    #
-    # The keys in the JSON string are unordered due to the nature of hashes.
-    #
-    # The <tt>:only</tt> and <tt>:except</tt> options can be used to limit the
-    # attributes included, and will accept 1 or more hash keys to include/exclude.
-    #
-    #   { :name => "Konata Izumi", 'age' => 16, 1 => 2 }.to_json(:only => [:name, 'age'])
-    #   # => {"name": "Konata Izumi", "age": 16}
-    #
-    #   { :name => "Konata Izumi", 'age' => 16, 1 => 2 }.to_json(:except => 1)
-    #   # => {"name": "Konata Izumi", "age": 16}
-    #
-    # The +options+ also filter down to any hash values. This is particularly
-    # useful for converting hashes containing ActiveRecord objects or any object
-    # that responds to options in their <tt>to_json</tt> method. For example:
-    #
-    #   users = User.find(:all)
-    #   { :users => users, :count => users.size }.to_json(:include => :posts)
-    #
-    # would pass the <tt>:include => :posts</tt> option to <tt>users</tt>,
-    # allowing the posts association in the User model to be converted to JSON
-    # as well.
