Out of curiousity, can you name some weakly typed languages with your definition?

    Assembly, C, C++ (where it copies C), and Java all have weak type systems, according to this definition.

    Don't mistake a static system which requires knowing type information at compile time with a strong system which, when it has any meaning at all, usually means that you can't (or don't need to) subvert the type system.

    If you have to cast to do your work, you have a weak type system.

      Under your definition it does not sound as if any languages are strongly typed. I have always heard people refer to C, C++, and Java as "strongly typed" languages. Somebody's making a mistake with the definitions here though, and I have trouble accepting a definition of "typing" which does not allow any languages to be strongly typed...

        There are languages with good static type systems, including Haskell and ML. I suspect the people you overheard know nothing about these languages.

        For more information, see MJD's Strong Typing lecture slides or almost every other discussion on Lambda the Ultimate.
