=head1 NAME

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

=head1 SYNOPSIS

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

=head1 DESCRIPTION

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.

=head2 Methods

=head3 new

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

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