I'm not sure if it's definitely necessary, but the stated use case was for
factories / named constructors. PHP only has one constructor per class, so it's
not uncommon to have static createFromX methods.
Since this will eventually evaluate as "new Foo(42)":
<< Foo(42) >>
The idea is that this would be available to call a factory instead:
<< Foo::fromRoman('XLII') >>
The neat thing being that by limiting the options to this, you can still
extract a class name for every annotation.
I say "eventually", because as proposed, this won't actually happen until you
explicitly ask for the "instance" of the annotation. See previous examples.
