Re^2: "my" cost

Is 0.00722599029541 seconds really a long time?

It is if you need to iterate through the loop enough times!

However, I don't concern myself with how long things take until they take "too long". At that point, I look to see why they are taking so long and what we can do about it.

It is if you need to iterate through the loop enough times! How do you figure that? If you're going to loop a million times, it's still only takes 0.0007 s cumulatively. It will only add up to 7 s if you do a billion passes of the loop. If you're doing something a billion times in Perl, it's going to take an hour, a day, or more. An extra 7 s isn't going to matter. This is the point where you offload the work to C or something, not move a `my`.	[reply] [d/l]
