Data.Universe.Some

Contents

Synopsis

Documentation

Auxiliary class to power Universe (Some f) instance. (There are no good reasons to use FlexibleInstances).

Laws are induced via Universe (Some f) instance. For example:

elem x universe ==> elem (Some f) universeSome

As GEq cannot be written for phantom Functors, e.g. Const or Proxy, they cannot have UniverseSome instance either.

Note: The Some type is imported from Data.Some, i.e. maybe either from Data.Some.Newtype (default) or Data.Some.GADT modules.
