So, then the real rules order is:
* If the argument name matches a route variable, we use it ($id in the
example)
* If not, and if there is a default value, and if the argument is optional,
we use the default value ($pi in the example)
* If not, and if the argument name matches a service name, we use it ($user
in the example)
* If not, we throw an exception
