Nonononono! Please not!!!!!! I realize more and more, that every type checking is a great potential danger to corrupt or even destroy a clear OO design!!! I am currently learning and using C++. Learning means here, upgrade my knowledge from C++ 1.2 -> ANSI C++. The same time I am learning and playing a little bit with Objective C. Although C++ is more mightier than ObjC, but it let struggle me all the time, because of its damned type checking. With all the nice features of C++, I am currently solving problems, I would not have with Ruby or ObjC..... :-( So please don't propagate type checking too much. Gimme freedom! :-) If I really want to put another object than a string into FTP#list, please let me do it. If my object reacts properly, ok! If not, my fault!!! :-)))) BTW: I don't think, the error message was not clear enough!!! > > -- gotoken \cle
