Why not improve your metaclass wrapping so it knows about properties and 
replaces them with properties containing wrapped functions?

That way you could avoid having to remember to write special code like 
this, and surely the whole point of using a metaclass is so that you can 
extract the special code and leave your class definition as clean as 
possible.
