Clearly it is desirable to have a minimal set of first-class things providing a richest possible set of second-class ones with minimal efforts. Thus comparing two languages one should take into account not what the first-class objects sets contain or not, but how productive and small they are. -- Regards, Dmitry Kazakov www.dmitry-kazakov.de
