read my sentence as "why T is a type constructor and T1 seems not to be?" look at the types: mkT 2 5 will return (2,5) whose type is "T a" mkT1 2 5 will return (2,5) whose type is "(a,b)". they return the same stuff with different types. Onle myT will return a type of type "T a". andrea _______________________________________________ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
