This package defines a type class for types with certain distinguished values that someone considers to be aesthetically pleasing. Such a value is commonly referred to as a default value.

This package exists to introduce artistic variety regarding the aesthetics of Haskell's base types, but is otherwise identical in purpose to data-default.
