Algebraic classes are type classes where all the methods return a value of the same type, which is also the class parameter.
Examples from `base`

are `Num`

and `Monoid`

.

F-algebras are functions `f a -> a`

, where the functor `f`

is called the signature, and the type `a`

the carrier.

This package relates these 2 concepts, and can create conversions between the two using Template Haskell. More specifically, it can generate:

signatures from algebraic classes

instances of algebraic classes from F-algebras.

This is useful because type classes are more commonly used in Haskell than F-algebras, but F-algebras are easier to work with, because they are just functions.
