synopsis: A class for monads which can keep a stack trace
category: Control, Monads
stability: experimental
description:
  This package defines a class for monads which can keep a monadic call trace.
  .
  . See 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 withLoc before every monadic statement in a module.
  .
  To invoke the preprocessor, add the following pragma at the top of a source file:
  .
  > {-# OPTIONS_GHC -F -pgmF MonadLoc #-}
  .
  together with an import for the @Control.Monad.Loc@ module
  .
  This package provides no implementation of the 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.
