Here, the fact that the function name is the same in all 10 cases is really important. Also, this approach is rather an exception than the rule in FXSL. If I remember well, it is used only for f:apply() and f:curry() Different overloads are used systematically, on a massive scale, to present "normal" F & O functions as higher order functions and as curried functions, that is to present their partial applications on a subset of arguments as a function. -- Cheers, Dimitre Novatchev --------------------------------------- To avoid situations in which you might make mistakes may be the biggest mistake of all.
