ZEND_CHANGES suggestion, part II

Hi again,

It would be helpful to summarize the difference between namespaces and 
classes in ZEND_CHANGES as well.  I see namespaces can have their own 
functions, constants and variables, like classes.  Namespaces can't be 
instantiated into objects, correct?  So access modifiers and 
constructors are not legal, and static is irrelevant as all functions, 
vars and constants are static.  Correct me if I'm wrong.

Regards,
Greg
