If you care for performance then *always* time your code (in this case the two alternative versions with and without array ops), because what Walter and docs say is always less important that what the reality is. I've yet to find situations where array expressions have given me a speed-up over the normal code generated by LDC (if performance is quite important then don't use DMD). Also note that currently array ops are quite buggy and slow when the arrays are short. Bye, bearophile
