Broken documentation?

[purew]

Documentation at http://package.elm-lang.org/packages/iosphere/elm-logger/1.0.1/Logger shows the following initialization code:

import Logger

loggerConfig : Logger.Config
loggerConfig =
    Logger.config Logger.Info

But this fails with a type-error. I had to specify the type as

loggerConfig : Logger.Config a 

(note the last a).
