@property

[Adam D. Ruppe]

I should add: if a function is not marked @property, it should 
not change at all: it should be callable with and without parens, 
including sometimes referring to the wrong thing, exactly like it 
is now.

I come to fix code, not to break it. Rewriting references to 
@property function names should fix all property related issues 
without breaking any existing code (except that which explicitly 
specified @property but depended on the wrong semantics, code 
which is arguably already broken, just like any other bug fix can 
do.)
