Dmitry Olshansky:

Who are those people that are not disabling bounds checks in system language ? :)

If you show D code on Reddit and you show to compile with -noboundscheck you hear some people growl. I don't remember this happening much in past. So I think the attitude toward disabling bound checks is changing.

-----------

Once some more logic for bound checks removal is in D, it can even be added a @bounded expression attribute:

foreach (immutable i; 0 .. a.length)
    a[@bounded i]++;

@bounded {
    foreach (immutable i; 0 .. a.length)
        a[@bounded i]++;
}

The purpose of @bounded is just to give a compile-time error if the compiler is not able to remove one (or more if used with the {} syntax) array bound check.
