It is the responsibility of the programmer to write *forward-compatible* code, i.e., code that does not make assumptions that are *likely* to break in the future. For instance, one can *reasonably* think that the domain of the `typeof` operator may expand.

Naturally, the programmer should be smart enough in order to make the difference between paranoia and common sense: this is part of the art of programming.
