-- $backend
-- NumHask imports Protolude as the prelude and replaces much of the 'Num' heirarchy in base.
-- Usage of 'Semigroup' and 'Monoid' has been avoided to retain basic compatability.
-- $instances
-- Re-defines the numeric tower.
--
-- Instances for 'Int', 'Integer', 'Float', 'Double', 'Bool', 'Complex' and 'Natural'are supplied.
--
