create my own property which passes parameters

[Igor Vartanov]

__property double a = {read=getA("a"), write=setA("a")};
__property double b= {read=getB("c"), write=setB("c")};

Actually I do not match this syntax to any I'm aware of. It's definitely not managed C++ __property. Neither it's plain VC++ __declspec(property) extension. So I wonder whether it's C++ at all.
