* NEW: '_operators' interface has been renamed as '_operator'.
* NEW: Arithmetic operators now can be applied on two objects with
different classes. One at least must implement the '_operator' interface.
* NEW: Each class that implements the '_operator' interface has now an
automatic priority that follows the load order. When a binary operator
has two objects that implement two different '_operator' interface, the
one having the highest priority is used.
* NEW: Implementing all methods in the '_operators' interface is not
mandatory anymore. If one method is not implemented, then it is replaced
by a function that raises a 'Type mismatch' error.
