For the second time I have put a bug like this:
def foo(int[] a) {
...
a.length = a.length - 1;
}
The length change can't be seen from the outside, because a is a struct passed
by value. You have to use foo(ref int[] a). I think I'd like this to be the
default behavior of dynamic array pass (disabled for example if you put an
foo(in int[] a).
Do you add this bug to your programs too?

Such bit may also be stored in the pointer, if they are aligned to 8 or 16
bytes.
