Now, if the type behavior is indeterminable from the type's structure, then structured equivalence imply weak typing = the behavior varies with the interpretation. Otherwise (the behavior is exhaustively determined by type's structure) the type system is weak. I don't really know ML, so I can only suggest that it falls into the first category. P.S. Strong typing became a kind of fashion. In these days almost any language claims to be strongly typed. -- Regards, Dmitry A. Kazakov http://www.dmitry-kazakov.de
