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.
