- types in haskell must be capitalized (maybe a better syntax error message would be nice, i ran into the same pb) - "t" is a free variable, so you can't write this. Either write: type Pair t = (t,t) or type Pair = (Int,Int) or even type Pair t1 t2 = (t1, t2) _______________________________________________ Haskell mailing list [EMAIL PROTECTED] http://www.haskell.org/mailman/listinfo/haskell
