Indicates that a method should be customized. Any method marked
with this annotation will be sent to the class level customizer
rather than the normal "add/lookup/remove" format that it would
normally be mapped to. This is useful if there is some sort of
special processing that needs to be done, or if a method on an
interface looks like one of the special method types but in fact
is not. It is an error for this to be placed on a method where
the class does not have a
Customizer that will be detected
only at runtime
