[Haskell-cafe] classes question

Hi. I am using Hugs 98 I have that piece of code: class PlusTimes a where plus :: a -> a -> a instance PlusTimes Int where plus x y = x + y when I run : "plus 2 3" I get this error: ERROR - Unresolved overloading *** Type : (Num a, PlusTimes a) => a *** Expression : plus 2 3 What am I doing wrong? Thanks. -- View this message in context: http://old.nabble.com/classes-question-tp26271257p26271257.html Sent from the Haskell - Haskell-Cafe mailing list archive at Nabble.com.
