I think you may be overestimating the severity of the "breakage" that
applies to the WashNGo package.

In Haskell2010 a number of module locations were renamed in order to reduce
clutter.  For example, IO became System.IO, List became Data.List and Monad
became Control.Monad.

I'm pretty sure that updating all of these module names will fix the
problem.  No one has bothered because the package is very old and there are
more suitable alternatives these days.
