I like this quite a lot... only problem being that signals are unique to processes, not objects, so if you try to instantiate more than 1 of your objects and attach it to a signal handler, only the last object attached will actually have the signal handler installed.

For example, if I have this code: 

package Obj;

sub new {
    my $class = shift;
    my $self = { @_ };
    bless $self, $class;
    $self->set_signal_handlers;
    $self;
}

sub name {
    shift->{'name'};
}

sub set_signal_handlers {
    my $self = shift;
    $SIG{USR1} = sub { $self->handle_USR1() }
}

sub handle_USR1 {
    my $self = shift;
    print "handling USR1 for ", $self->name, "\n";
}


package main;

my $obj1 = new Obj(name => 'obj1');
my $obj2 = new Obj(name => 'obj2');

while (1) { }

and I run this little script, then give it a USR1 signal, the only object that's ever going to catch that signal will be obj2. See what I'm saying?

All the same, it's a nice little method. :)
