The letter then mentions C++ as such a language. I would guess the opposite, that most OOPLs retain class information at run time. Which other (widely known) OOPLs lack this feature? Eiffel, I think. Any others? (Of course, there are various ways to maintain or determine class membership in C++, but the language itself does not specify one.) -- Patrick Logan, uunet!mntgfx!plogan -or- plogan@dad.mentor.com Mentor Graphics Corp. 8500 SW Creekside, Beaverton, Oregon 97005-7191
