Is there any fundamental reason Julia doesn't support abstract multiple inheritance?

Question

For example, I want to be able to do something along these lines: ``` abstract Tree abstract SupervisedModel type DecisionTree <: Tree, SupervisedModel ``` This currently isn't possible in Julia. Is this due to any fundamental reasons, or is it simply not implemented yet?

Accepted Answer

This issue is currently under discussion. It appears that the implementation is complex and results in many edge cases, but that there are no fundamental reasons why this couldn't be a language feature: https://github.com/JuliaLang/julia/issues/5
