synopsis: A class for monads which can keep a monadic call trace
category: Control, Monads
stability: experimental
description:
  This package defines a class for monads which can keep a monadic call trace.
  .
  * See the blog post <http://pepeiborra.posterous.com/monadic-stack-traces-that-make-a-lot-of-sense> for more information.
  .
  A preprocessor is provided which can insert calls
  to "Control.Monad.Loc.withLoc" before every monadic statement in a module.
  To invoke the preprocessor, add the pragma @OPTIONS_GHC -F -pgmF MonadLoc@  at the top of your Haskell files  together with an import for the "Control.Monad.Loc" module
  .
  This package provides no implementation of the "Control.Monad.Loc.MonadLoc" interface.
  Currently the only package that does so is @control-monad-exception@,
  but any other package can implement it and provide monadic call traces.
