bidirectional arrows, bijective functions, and invariant functors

Haskell bidirectional arrows, bijective functions, and invariant functors

Representations and operations for bidirectional arrows (total isomorphisms: an arrow paired with its inverse). Classes for invariant functors and monoidal functors. Includes a number of useful bijections and operations, as well as interoperability with related packages.

See also: semigroupoids, TypeCompose, lens, semi-iso, partial-isomorphisms, and Piso packages.
