Synopsis:       yet another prelude - a simplistic refactoring with algebraic
                classes
Description:    A simple refactoring of the Prelude numeric classes,
                aiming to escape from the restrictive bundling of
                operations in the standard numeric classes, while
                preserving backward compatibility for clients.
                This is done by adding algebraic classes as superclasses
                of the Haskell 2010 numeric classes, yielding the
                following class hierarchy (grey classes are unchanged):
                .
                <<https://raw.githubusercontent.com/RossPaterson/yap/refs/heads/main/images/hierarchy.svg>>
                .
                "Prelude.YAP" is an almost-compatible replacement
                for the standard Haskell Prelude, as long as you're
                not defining instances of the numeric classes (though
                defaulting will be affected).  When importing it, use
                .
                @{-# LANGUAGE RebindableSyntax #-}@
                .
                This will turn off the implicit @Prelude@ import and
                attach various syntax to the new definitions.
                .
                "Data.YAP.Algebra" contains just the new classes;
                you'll need to import it if you want access to the
                new names, including to define instances.
                .
                Other modules contain instances for the existing types
                @Complex@ and @Ratio@.
                Further examples are in the @yap-examples@ package.
