 It seems that the `No module named ... is imported` message produced in
 response to out-of-scope identifiers doesn't account for qualified
 imports. For instance,

 {{{
 $ ghci
 GHCi, version 8.2.1: http://www.haskell.org/ghc/  :? for help
 Loaded GHCi configuration from /home/ben/.ghci
 λ> import qualified Data.Maybe as M
 λ> M.fromJusr

 <interactive>:2:1: error:
     Not in scope: ‘M.fromJusr’
     Perhaps you meant ‘M.fromJust’ (imported from Data.Maybe)
     No module named ‘M’ is imported.
 λ>
 }}}

 I suppose there is the question of whether we consider `M` to be a
 "module" here; I would argue that I imported it and therefore the message
 is at very least a bit misleading.
