My recollection of reading the spec is that a D compiler is allowed to

I don't know if this is neat or nasty for a compiler to do so.
OT : Is there a DMD switch to disable bound check exceptions ? This way I
wouldn't have to rely on pointers so much.
If you always want DMD never to bounds check for specific code, you just
can write "a.ptr[index]" instead of "a[index]" (when a is an array).
That's because array.ptr returns a pointer to the first element, and
using [] on a pointer works exactly like C pointer math. The good thing
about this is that you still can use array slices and the .length field,
so the code most likely is less messy than the C version would be.
