default Build Status Maven Central

A typeclass approach for default values in Scala. The topic of much scorn in Haskell, I find the existence of this typeclass to be superior to the general use Monoid everywhere as though it was a default value.

Default exists to allow you to have something that expresses what you want, even if it might not be what you actually need.

Default exists as a typeclass that allows Default[A].default: A, it exposes in the package object def default[A: Default]: A which you will likely find useful to remove the ceremony of summoning the typeclass to use.

Quick Start
