ghci's :info and :browse break encapsulation
In ghci, :info shows representations of abstract data types. I consider this undesirable, since it breaks abstraction and confuses users.
Example:
Prelude> :m +Data.Unique
Prelude Data.Unique> :i Unique
newtype Unique = Data.Unique.Unique Integer
-- Defined in `Data.Unique'
I would expect it to behave in the same way as Haddock does, i.e. just show "data Unique".
Same about the :browse command.
