Good point. "Missing casts" are really the mass of the warnings. And
adding hundreds of casts will make blind situations you described.
I think to bring in better cast statements, to give the compiler more
information.
Something like
sign(), unsign(): e.g. long->ulong, uint->int
shrink()        : e.g. int->short, ulong->ubyte, double->float
If the compiler knows better about the users intention, he could warn
better.
