could the compiler avoid "with" pitfalls?
now the compiler attach a property to the closest "with" where it finds it. the compiler could check if the property appears in another "with" of the "with" stack and produce a message (hint, warning or error, which may be configurated). is not it a way to make the "with" safe?
