No, I mean something built-in, and generally invisible. See ObjectPascals.

Nope. It has to be the other way round: when a programmer doesn't care of avoiding some integer-related bugs he/she/shi can add a "-release" to the compilation arguments. Forcing the programmer to use an ugly and long syntax everywhere in the program isn't a way to avoid that class of bugs in most D programs.
