extensible optionally-pure exceptions; documentation

This library supports monads that can throw extensible exceptions. The exceptions are the very same from Control.Exception, and the operations offered very similar, but here they are not limited to IO.

This code is in the style of both transformers and mtl, and is compatible with them, though doesn't mimic the module structure or offer the complete range of features in those packages.

This is very similar to ErrorT and MonadError, but based on features of Control.Exception. In particular, it handles the complex case of asynchronous exceptions by including mask in the typeclass. Note that the extensible extensions feature relies the RankNTypes language extension.

This package provides the documentation for a library for the Haskell programming language. See http://www.haskell.org/ for more information on Haskell.
