Critical bugfix in module Safe (Opcode). Version increased, changelog and test added.

This example hacks outside environment:

package My::Controller;
use strict;

sub jopa { return "jopa\n"; }

package main;
use Safe;

my $s = new Safe;

my $ok = $s->reval(q{
    package My::Controller;
    sub jopa { return "hacked\n"; }

    My::Controller->jopa();
});

print My::Controller->jopa();
