  # Returns the passed-in argument, +x+; the identity function. This method
  # is provided for convenience since it is used as the default behavior for a
  # number of property functions.
  #
  # @param [Object] x, a value.
  # @return [Object] the value +x+.

 # Returns <tt>self.index</tt>. This method is provided for convenience for use
 # with scales. For example, to color bars by their index, say:
 #
 # <pre>.fill_style(Rubyvis::Colors.category10().by(Rubyvis.index))</pre>
 #
 # This method is equivalent to <tt>lambda {self.index}</tt>, but more
 # succinct. Note that the <tt>index</tt> property is also supported for
 # accessor functions with {@link Rubyvis.max}, {@link Rubyvis.min} and other array
 # utility methods.
