The Module FlatCurryGoodies provides auxiliary functions to process
FlatCurry programs. An functions that returns a list of all construtor
names that are defined in a program can be written as follows:

     import FlatCurry
     import FlatCurryGoodies

     constructorNames :: Prog -> [QName]
     constructorNames prog =
       [ name | typ <- progTypes prog, name <- consNames typ ]
      where
       consNames typ =
        [ consName cons | not (isTypeSyn typ), cons <- typeConsDecls
typ ]

Cheers,
Sebastian
