Dear Hugs maintainers, the version of hugs in the repository stumbles over the following program (which the february 2001 version compiles without problems):

data Dir = C | N | NE | E | SE | S | SW | W | NW deriving (Eq, Read, Show, Enum, Ord)

instance Num Dir where a + b = toEnum (fromEnum a + fromEnum b) a - b = toEnum (fromEnum a - fromEnum b)

Parsing ERROR error.lhs:6 - Syntax error in declaration (unexpected `-') Just to let you know ... Cheers, Ralf
