Work in progress!
We start with some very basic examples, for this we consider all the classes not to be inherited by ANY.
Example set
Basic cases of direct repeated inheritance
The following set of example will base on class B:
class B feature f: INTEGER g do f := f + 1 end end
class D1 inherit {NONE} B rename f as f_1, g as g_1 end B rename f as f_2, g as g_2 end feature end
An object of class D1 contains two physical attributes (f_1 and f_2). A call to feature g_1 results in f_1 being incremented and a call to g_2 increments f_2.
