 I propose to suggest in completion only modules the user already loaded
 into the context. The completion should look like this

 {{{
 Prelude Data.List> :m -
 Data.List  Prelude
 }}}

 instead of this

 {{{
 Prelude Data.List> :m -
 Display all 728 possibilities? (y or n)
 }}}

 I have already written a patch, but it requires addition of one function
 into haskeline library. Actually, this function can be put into ghci, but
 it fits more naturally in haskeline. I have created a ticket in haskeline
 trac http://trac.haskell.org/haskeline/ticket/109
