I seem to be the only one who sees Walter's side of things in this thread
:o)
Why the hell would the compiler allow that to begin with? Why bother
implementing nonnull references only to allow the entire system to be
broken?
Because D is a practical language that let the programmer do whatever he
wants, even shoot his own foot if he wants to. Doing so just isn't as
implicit as in C.
Walter understands there are some cases where you want to override the
type system, that's why casts are in D, too many optimizations rely on it.
