An implementation of "A Categorical Programing Language".
version 0.0.5
====================

  This package is an implementation of "A Categorical Programing Language"
  (CPL for short)[1][2] written in Haskell.

  CPL is a functional programming language based on category
  theory[3]. Data types are declared in a categorical manner by
  adjunctions. Data types that can be handled include the terminal
  object, the initial object, the binary product functor, the binary
  coproduct functor, the exponential functor, the natural number object,
  the functor for finite lists, and the functor for infinite lists.
  Each data type is declared with its basic operations or
  morphisms. Programs consist of these morphisms, and execution of
  programs is the reduction of elements (i.e. special morphisms) to
  their canonical form.
