Similar for mtl library. Some of the modules are documented, but many aren't
at all. This has been a problem for me with the new Control.Monad.XYZ.Lazy
vs. ...Strict stuff. I honestly don't have a clue what exactly is lazy or
strict here. (I know there has been some discussion about this but I didn't
understand most of it.) Another problem are the more obscure features of
Control.Monad.Writer.Class, such as listen and pass methods. (For these I
finally found an explanation in 'All About Monads'.)
