"on"
my $cb = $e->on(foo => sub {...});

$e->on(foo => sub {
my ($e, @args) = @_;
...
});
"once"
my $cb = $e->once(foo => sub {...});
Subscribe to event and unsubscribe again after it has been emitted once.
$e->once(foo => sub {
my ($e, @args) = @_;
...
});
"subscribers"
my $subscribers = $e->subscribers('foo');
All subscribers for event.
