Despite several mentions in the manual, lots of php 5.3 code uses this with
instanceof or in function signature (eg: Doctrine 2).
If you don't want to support this in the future, could this be cleaned-up in
5.4?
( the longer you wait, the more you break )
Possibly by creating a interface called Closure, and change the name of the
actual class + implement the Closure interface..
