when I interpret my file Utilities/ChoiceMonad.hs from ghci-haskline I get
the following message:
[2 of 2][Compiling Utilities.ChoiceMonad ( Utilities/ChoiceMonad.hs,
interpreted )
ghci-haskeline: panic! (the 'impossible' happened)

Please report this as a GHC bug: http://www.haskell.org/ghc/reportabug
but if i do "ghc --make Utilities/ChoiceMonad.hs" that works and I can
then load it with ghci-haskline, at least until I modify it and need to
compile again.
