C> Isn't this the same ambiguity you get with regular inheritance?

 yes, do you remember what do ruby with an included class ?

 In my example you have internally

  A ===> [M] ===> Object

 this give  A < [M]
 and it has B < Array

 ([M], B) -- (A ,Array) is ambiguous

 You really think that it's different from multi-dispatch ? :-)))))
