Polymorphism in Elixir

Yes, we’re both solving the same problem: defining a default comparison for a type.

Here’s how I might implement the homogeneous sort:


def sort(list, ord \\ Funx.Ord) when is_list(list) do

Enum.sort(list, Ord.Utils.comparator(ord))

end

This lets the caller sort a list using the domain’s default ordering or pass in a different Ord when needed. It supports cases where the same type needs multiple comparison strategies. It also allows Ord composition, making it easy to build more complex ordering logic.
