in thread Can't localize lexical variable $var at...

You did not understood what I meant.
{ my $var=2; sub inc {return $var++} sub dec {return $var--} } print inc; print dec;
Those subs see that $var which is not seen outside that block, and perl doc says this is a trick to have private static variables.

    Now you are talking about closures. I do not see how that is relevant to localized globals?

    Makeshifts last the longest.

      Because I am sad I can not localize lexicals (declared via 'my'), and this item was at the very beginning of my question.

      Thanks to all people (including you) that helped me understanding this and related things.

      Courage, the Cowardly Dog.
