As my last contribution to this thread today, I just did what could
have answered my question about extends in the first place. I did
some timing on using the simple extend that replaces i=i+1 with
i.Incr.
It turns out that using i.Incr takes just over three times as long
to execute as i=i+1 (on Windows).
This is of course only of importance when used in a loop that calls
the function millions of times. And even then is the time needed to
execute so incredibly short that difference in execution time
basically still means nothing.
For some apps you can see improvements by reducing function calls in
the order of thousands or even just hundreds, never mind millions.
I've seen real-world measurable speed ups by manually inlining
methods and otherwise reducing function calls by using pointers. I
mean "seen" literally, saving just a few milliseconds per frame in a
game really adds up for example - even a seemingly modest 10FPS jump
can turn an unplayable game into an enjoyable experience.
