Summary: Reflected (swapped) operations overridden by subclasses

Initial Comment:
In Python 2.5b2 Documentation:
   Python Reference Manual
   Section 3.4.7 Emulating numeric types
   <http://docs.python.org/dev/ref/numeric-types.html>

Note to description of __radd__, __rsub__, etc.
specifies that "this method will be called before the
right operand's non-reflected method."

Should replace RIGHT with LEFT here. The correct phrase
is "this method will be called before the LEFT
operand's non-reflected method."

For example, reader should clearly understand that
"RIGHT.__radd__ will be called before the LEFT.__add__"
in case when type(RIGHT) is subclass of type(LEFT).
