Speaking of which, I have been wondering why POE is implemented with a whole bunch of names instead of references. Any reason for that design decision?Example: $kernel->post('resolver', 'resolve', 'response', $host, 'A', 'IN'); Wouldn't it have been cleaner and less error prone to have something like this: $resolver->resolve(&response_callback, $host, 'A', 'IN'); Notice that this way, the compiler can catch most misspelling.
POE has grown organically, building up from simple ideas with simple extensions. Not all of its growth is perfect.
There's a new project, POE::Stage on the CPAN. I hope it will formalize some of the stronger component design patterns that have arisen over the years. It includes a DNS resolver, but it's not as featureful as POE::Component::Client::DNS.
By the way, your cleaner example contains an error. :) -- Rocco Caputo - http://poe.perl.org/
