-Merges path with C<< $c->request->base >> for absolute URIs and with

-object. If any args are passed, they are added at the end of the path.

-contain GET parameter key/value pairs, which will be appended to the URI
-in standard fashion.

+
+A Catalyst::Action object representing the Catalyst action you want to
+create a URI for. To get one for an action in the current controller,
+use C<< $c->action('someactionname') >>. To get one from different
+controller, fetch the controller using C<< $c->controller() >>, then
+call C<action_for> on it.
+
+You can maintain the arguments captured by an action (e.g.: Regex, Chained)

-Note that uri_for is destructive to the passed hashref. Subsequent calls
-with the same hashref may have unintended results.

+ # For the Foo action in the Bar controller

-which will be resolved to a path using
-C<< $c->dispatcher->uri_for_action >>; if the first element of
-C<@args> is an arrayref it is treated as a list of captures to be passed
