Methods that appear for instances of a particular class may be defined
in ancestors of that class (or included modules, either of the class
or its ancestors), rather than than in the class itself. In this case
__id__ and __send__ are Kernel methods (probably documented under
Object, rather than Kernel) and denominator is, I think, defined in
Numeric.
