devel/p5-Lexical-Persistence 1.023_1 DragonFly

Lexical::Persistence does a few things, all related. Note that all the behaviors listed here are the defaults. Subclasses can override nearly every aspect of Lexical::Persistence's behavior.

Lexical::Persistence lets your code access persistent data through lexical variables. This example prints "some value" because the value of $x persists in the $lp object between setter() and getter().

    use Lexical::Persistence;

    my $lp = Lexical::Persistence->new();
    $lp->call(\\&setter);
    $lp->call(\\&getter);

    sub setter { my $x = "some value" }
    sub getter { print my $x, "\\n" }
