i find the anchor pattern both a royal pain and too strict, i dont generally
care to bind classes between two resources but instead just before some
resource or class
class wrapper {
include one, two, three
Class["one"] -> Class["two"] -> Class["three"] -> Class["wrapper"]
}
at this point 'include wrapper' will have those 3 classes and their
resources completed before anything that requires the wrapper class
this is often sufficient enough and satisfies 'just enough ordering hints'
to me.
