MasonX::Interp::WithCallbacks subclasses HTML::Mason::Interp in order to
provide a Mason callback system
Callbacks may be either code references provided to the
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.
