No I am not missing it. I think I need to explain why I am doing
all of this.
I am currently looking for rules and programming styles that
would reduce number of bugs and/or make my program run or at
least compile faster. So I read that you should prefer pre
increment to post increment. So I investigate and concluded that
for the most part it doesn't matter. But that "most if the time"
thing bugged me over a month. I investigated more and I was
jumping constantly between it matters and it doesn't matter.
Every time I jump to it matters the amount of matters shrinks. So
now I am on the quest to quantify how much it matters and if it
doesnt matter I could say to anybody who repeats it to eat a bowl
In C++ world always writing ++var can save some perf when using
with overloaded operators. In D world it has no result on
resulting binary and the use of these operators is reduced with
