Description
Allow monad transformers to be run/eval/exec in a section of conduit rather then needing to run across the whole conduit. The circumvents many of the problems with breaking the monad transformer laws. For more information, see the announcement blog post: http://www.yesodweb.com/blog/2014/01/conduit-transformer-exception
This module was added in conduit 1.0.11.
