MasonX/Interp/WithCallbacks version 1.19

MasonX::Interp::WithCallbacks subclasses HTML::Mason::Interp in order to provide a Mason callback system built on Params::CallbackRequest. Callbacks may be either code references provided to the new() constructor, or methods defined in subclasses of Params::Callback. Callbacks are triggered either for every request or by specially named keys in the Mason request arguments, and all callbacks are executed at the beginning of a request, just before Mason creates and executes the request component stack.

This module brings support for a sort of plugin architecture based on Params::CallbackRequest to Mason. Mason then executes code before executing any components. This approach allows you to carry out logical processing of data submitted from a form, to affect the contents of the Mason request arguments (and thus the %ARGS hash in components), and even to redirect or abort the request before Mason handles it.
