=C2=A0 =C2=A0 Seems difficult to unify that in one concept.


That seems inaccurate to me:

C1 =3D Class.new Object
C2 =3D Class.new C1
C3 =3D Class.new C2

I was alluding to multiple inheritance, meaning a class
inherits _directly_ from more than one superclass.
T= he point is that inheritance may be done with include + extend from a modul= e.=C2=A0


M1 =3D Module.new
M2 =3D Module.new
C4 =3D Class.new { include M2, M1 }
