{-# LANGUAGE NoImplicitPrelude #-}

-- | A DSL for describing and computing with combinatorial species.
--   This module re-exports the most generally useful functionality;
--   for more specialized functionality (for example, computing
--   directly with cycle index series), see the various sub-modules.
--
--   Note that this library makes extensive use of the numeric-prelude
--   library; to use it you will want to use -XNoImplicitPrelude, and
--   import NumericPrelude and PreludeBase.
--
--   For a friendly introduction to combinatorial species in general
--   and this library in particular, see my series of blog posts:

-- $DSL
-- The combinatorial species DSL consists of the 'Species' type class,
-- which defines some primitive species and species operations.
-- Expressions of type @Species s => s@ can then be interpreted at
-- various instance types in order to compute with species in various
-- ways.

-- $synonyms
-- Some synonyms are provided for convenience.  In particular,
-- gramatically it can often be convenient to have both the singular
-- and plural versions of species, for example, @set \`o\` nonEmpty
-- sets@.

-- $types
-- Many of these functors are already defined elsewhere, in other

-- naming/instance schemes, etc., we just redefine them here.
