How are traits specific to being a functional language rather than an OO language though?

I mean, I don't see anything horribly functional-language-specific about your trait example.

It wasn't my example, but it's just disproving the notion that FP somehow means you need to write big if statements to dispatch your functions.

Traits are not functional-language specific except in that they are often used in FP to solve problems similar to those one might use inheritance to solve in OOP.
