Persistent lexical variable values for arbitrary calls

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" }
