numeric-prelude-0.4: An experimental alternative hierarchy of numeric type classes

PortabilityAbstract concept of a Monoid.
Safe HaskellNone



Will be used in order to generate type classes for generic algebras. An algebra is a vector space that also is a monoid. Should we use the Monoid class from base library despite its unfortunate method name mappend?



class C a whereSource

We expect a monoid to adher to associativity and the identity behaving decently. Nothing more, really.

(<*>) :: a -> a -> aSource
