Hi. Please proofread whether the following statement (written by me) about Mixin in Ruby is true: “Mixin is the way to incorporate certain functionalities into a class without messing up inheritance hierarchy. Especially, Mixin in Ruby is a clever way of implementation inheritance.” I’ve seen no article mentioning implementation inheritance when explaining mixin though I believe it is especially in contrast with interface inheritance.

But be aware that even Mixins can be confusing for the unwary sometimes there was a recent thread about it.
