I have timed tree versions of that little code: D without = void: first run 1.85 s, successive ones: 0.11 s D with = void: first run 0.24 s, successive ones: 0.10 s C compiled with DMC: first run: 0.10 s, successive ones: 0.06 s C compiled with GCC: first run: 0.07 s, successive ones: 0.05 s (Compilations with no arguments. GCC compiled with -s -Os). So that huge executable is bad for the speed too. Bye, bearophile
