yap: yet another prelude - a simplistic refactoring with algebraic classes
A simple refactoring of the Prelude numeric classes, attempting backwards compatibility for clients by defining a few algebraic classes as superclasses of the Haskell 98 numeric classes. This yields the following class hierarchy (grey classes are unchanged):
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, turn on RebindableSyntax
.
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 some example instances, including
for the existing types Complex
and Ratio
.
