@hackage acme-omitted1.1.0.0

Purely functional omitted content for Haskell

Standard Haskell lacks the ability to express the notion of "omitted content", making it impossible to distinguish the truly "undefined" and the merely "omitted".

acme-omitted implements a universal definition of "omitted" and provides means of observing whether a definition has been omitted or if it is truly undefined.

The library is standards-compliant, type-safe, and user-friendly.
