Hi Tim,

This looks interesting, but I notice it says that the closure can access=
 =E2=80=9Cprivate properties=E2=80=9D:

> This means that Closures in property default values may access private=
 properties, methods, and class constants of the class where they are de=
fined

I assume this means private *static* properties since it couldn=E2=80=99=
t be attached/bound to a specific instance? (Must be static?)
=E2=80=94 Rob
