Hi all, We currently have in the Data.Maybe module from base: fromJust :: Maybe a -> a which newbies often find using hoogle or other search tools and is a huge trap. *Every* usage of the above can be replaced by using fromMaybe :: a -> Maybe a -> a which forces the user to provide a default value for the case where the Maybe a is a Nothing. The idea would be to deprecate fromMaybe for 7.12 and remove it completely later. Comments?
