Consistent set of utility functions for Maybe, Either, List and Monoids.

Easy to use set of utility funcions, implementing a Data.Maybe like interface for other common types like Either, List, Bool, Tuple or even members of the Monoid type class.

Also features a set of conversion functions between all these types using sensible defaults.

Most of these functions are one liners, and this library started out as a self-educational project, which nevertheless proved to to be useful on its own right.
