--- Comment #9 from Benjamin Thaut <code at benjamin-thaut.de> ---
Please consider that you will scare of useres that care for maximum performance
(gaming, embended) if a noboundscheck does not turn off all bounds checks. If
you really care about performance you will always be wondering how much time
you loose from boundschecks in safe code, especially on mobile platforms
branches can be very expensive. Additinally you should not take the "tight loop
optimization" idiom to seriously. Modern optimized code bases often have a
"general slowness" problem. Nothing is really the hot spot, and almost all code
just runs to slow.
