Includes and imports in handlers
Notifying a dynamic include such asinclude_taskas a handler results in executing all tasks from within the include. It is not possible to notify a handler defined inside a dynamic include.
Having a static include such asimport_taskas a handler results in that handler being effectively rewritten by handlers from within that import before the play execution. A static include itself cannot be notified; the tasks from within that include, on the other hand, can be notified individually.
