I see Eiffel allows multiple inheritance

found any details of the method resolution order. Python does C3
linearization (invented by the Dylan folks), but as I recall both C++ and
Eiffel date from before that was invented.

C3 can be quite confusing.
I am pretty sure very few would have guessed the output
from this one:
$ type fun.py
class A:
     def m(self):
         print('Hi from A')
class B(A):
     def test(self):
         super().m()
class C(A):
     def m(self):
         print('Hi from C')
class D(B,C):
     pass
o = D()
o.test()
$ python fun.py
Hi from C
