Re^3: Impact of special variables on regex match performance

Not using those special variables (or rather not have them seen by perl ) isn't an option in the real project

Of course it is.

It doesn't mean you can do better. If you are using $` and $' on every match you make, it doesn't matter: any alternative will make you pay the price.

But if you're using $` and friends on some matches, then /p, @- and @+, and adding more captures in your patterns classical alternatives.

Yes, I didn't mean to say that there are no technical alternatives to my predicament. The obstacles are more organizational in nature. Thanks for the help.	[reply]

Well, if you cannot avoid using $' and $` in your program, you cannot avoid the costs that come with it. Just wishing the costs would go away isn't going to work.	[reply]
