Hi Anthony, I really like the idea. But I'd prefer the following syntax:
public function __construct(~HttpKernelInterfaceForClientIp $parent) { $this->parent = $parent; } Reasons: * A passed object does not have to explicitly implement the interface, but only implicitly ("practically", "more or less"). The tilde conveys that semantic very well. * As you mentioned, brackets are (IMO too) close to generics.
