cond: Basic conditional and boolean operators with monadic variants.

[ bsd3, control, library, logic, monad ] [ Propose Tags ]

This library provides:

  • Implementations of various overloaded conditional operations

  • Lifted monadic variants of those operations and common boolean operators

  • A typeclass for boolean algebras.

Feel free to send ideas and suggestions for new conditional operators to the maintainer.

Monadic looping constructs are not included as part of this package, since the monad-loops package has a fairly complete collection of them already.
