C++ "Addition"(wouldn't it be cool if...)

Hey, I was takin'' a look at a C# book, and the language has some cool features. One of them was a get/set type of member function dealio, and it was kinda cool. Instead of defining functions like this: class Point { GetX (); SetX (); ... } you did something like this: class Point { get m_X { return (m_X); } set m_X { return (m_x); } } or something like that, and then you just did this: Point.X = 4; whatever. Doesn''t matter anyway... that got me to thinking, though. I know you can return a reference to an object and use that return paramter as if it were an outside access to a member. Like this: Point.X() = 4; f = Point.X(); ok, we got that. now wouldn''t it be cool if we could write an operator called something like member()= or ==member() and it would give us access to a member? Like this: class Point { operator X()= (parameter) { myX = parameter; } operator ==X() (parameter) { // return true if x == parameter. } } then you could just do this: Point.X() = 4; f = Point.X(); then you could do bounds cheking and stuff. i am sense making? tinking me am not.

but his point is that it would be nice if it were possible. I agree, though you wouldn''t want to overuse it. Actually I assume (never looked into it) that java works that way for String and the array classes, both of which have a .length that you probably aren''t allowed to change.
