  • For those wondering why subclassing won't solve this, Section 2.3 also says this: “Each of the operands of a mixin composition C_0 with ... with C_n, must refer to a class. The mixin composition mechanism does not allow any C_i to refer to an abstract type. This restriction makes it possible to statically check for ambiguities and override conflicts at the point where a class is composed.” Commented Jul 28, 2017 at 18:19
