Currently only a limited set of scalar arguments to HTTP resources are supported: strings, ints, floats and bools. Anything else requires creating a custom "extractor."

It should be possible to use custom classes as parameter type to the #[Method] annotated functions of HTTP resources. Similar to dependency injection, the constructor arguments of new instances of these object arguments will be (recursively) populated according to the constructor definition using reflection.

One major difference with DI is that the object arguments may not be lazily instantiated, as incorrect HTTP arguments may indicate a security issue.
