Unison has a really nice docstring model, with helpers to interpolate values or function syntax! https://www.unisonweb.org/docs/documentation/

Function: addToBasket docstring: "Adds to basket". I see docs like this pretty often! Inform the user, or say nothing (which is reasonable!)

Given the choice between a docstring and a type signature, I find a docstring much more helpful on the first read (ideally I'd have both!)
