Description: callback aggregator for AnyEvent watchers
 The module allows You to create callback's hierarchy. Also the module
 groups error and result callbacks into one object.
 .
 Also the module checks if one callback was called by watcher or not.
 If a watcher doesn't call result or error callback, error callback will
 be called automatically.
 .
 Also the module checks if a callback was called reentrant. In the case
 the module will complain (using "carp" in Carp).
 .
 If a watcher touches error callback and if superior didn't define error
 callback, the module will call error callback upwards hierarchy.

=head1 DESCRIPTION

The module allows You to create callback's hierarchy. Also the module groups
error and result callbacks into one object.

Also the module checks if one callback was called by watcher or not.
If a watcher doesn't call result or error callback, error callback will be
called automatically.

Also the module checks if a callback was called reentrant. In the case the
module will complain (using L<Carp/carp>).

If a watcher touches error callback and if superior didn't define error
callback, the module will call error callback upwards hierarchy. Example:

lib/AnyEvent/Callback.pm  view on Meta::CPAN

    $self;
}

sub CBS {
    return AnyEvent::Callback::Stack->new;
}


=head2 error

Calls error callback. If the object has no registered error callbacks,
parent object's error callback will be called.

    $cb->error('WTF?');

sub error {
    my ($self, @error) = @_;

    $self->{ecalled}++;
