Hmmm, thinking about it today, maybe the following syntax would make
more sense?
package MyPlugin;
sub import {
my $caller = scalar(caller);
$caller->add_callback('init', 'my_setup', 'FIRST');
goto &Exporter::import;
}
That way we can make the positional parameter optional:
package MyPlugin;
sub import {
my $caller = scalar(caller);
$caller->add_callback('init', 'my_setup');
goto &Exporter::import;
}
It will make the docs simpler, because you can say "any callbacks
installed on behalf $self or superclasses of $self."
It also makes it more convenient for apps to install callbacks, because
they can just say
$self->add_callback('teardown', 'foo');
same as they would have done with the object-based callback mechanism.
