a mixin is created by creating a new class that is based on the class being extended?
I have a class library that is returning an instance of a class. How to apply the mixin pattern to an object that already exists?
Indeed, mixins, at least the mixins I've seen are no substitute for extension methods at all.
I like the |> pipe operator in F# but in terms of tool and user friendliness, nothing beats extension methods. Dot dot dot...
