I forgot to write in my main message. I'm mostly interesting in localization of variables with lixical scope. Because
A local just gives temporary values to global (meaning package) variables. It does not create a local variable ©perldoc
but my variable is not global( or package ) it's just hash reference.

That's why I have some doubts
