@property changes the typeof result (useful for introspection) 
[1][2]:

---
For the expression typeof(exp) where exp is an @property 
function, the type is the return type of the function, rather 
than the type of the function.
---

---
If the expression is a Property Function, typeof gives its return 
type.
