Not all signals follow the *Changed() naming convention, nor should they, so it becomes even less obvious in those cases.

Why do I need to know that it's a signal being emitted? How is that
"vital information"? I could just as well
invoke any other callback, but I find myself not exactly yearning for
being able to write
callback somethingHappened();
