autodie::Scope::Guard - Wrapper class for calling subs at end of scope

use autodie::Scope::Guard;
$^H{'my-key'} = autodie::Scope::Guard->new(sub {
    print "Hallo world\n";
});

This class is used to bless perl subs so that they are invoked when they are destroyed. This is mostly useful for ensuring the code is invoked at end of scope. This module is not a part of autodie's public API.

This module is directly inspired by chocolateboy's excellent Scope::Guard module.

new

my $hook = autodie::Scope::Guard->new(sub {});

Creates a new "autodie::Scope::Guard", which will invoke the given sub once it goes out of scope (i.e. its DESTROY handler is called).
