Array operation doesn't check array bounds

D has already array bounds, even to access single items. Array operations are bulk, so they need only one bound test, then they perform many operations without tests. So the bound time is often amortized, unless your arrays are very small. Otherwise you disable the tests with -release or -noboundscheck. I am rather sure Walter agrees about this.
