Mixin advantage

[Minkoo Seo]

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.

Sincerely,
