Latest on Hackage:1.1

This package is not currently in any snapshots. If you're interested in using it, we recommend adding it to Stackage Nightly. Doing so will make builds more reliable, and allow stackage.org to host generated Haddocks.

This philosophy behind this package is that it is often better to find out all of the errors that have occured in a computation and report them simultaneously, rather than aborting as soon as the first error is encountered. Towards this end, this module supplies a type of combinable error messages so that all of the errors from subcomputations can be gathered and presented together.

New in version 1.1: Removed Monoid instance for Doc (it should now be supplied by ansi-wl-pprint), added ErrorMessageOr type alias.
