I really don't know how hard it would be to add - but I would like to see it
added. One thing I don't like all that much is the untyped variables. It makes
things "easy" - but leads to some sloppy programming.
It also means you can't overload functions - at least not with the same number
of parms. Typing the constructor arguments is a good start. But expanding that
to other functions without breaking existing code might be more difficult.
