post/pre-increment/decrement and property

[Vidar Wahlberg]

Take the following code:
int _foo;
@property auto foo() {
         return _foo;
}
@property auto foo(int foo) {
         return _foo = foo;
}
void main() {
         ++foo;
}


This won't compile, and it sort of makes sense (at least to me), but is 
it (or will it in the future be) possible to achieve this in some way?

I like to encapsulate class/struct members this way so I can easily add 
validation of the value in the setter at a later time (granted, I can 
add getter/setter properties when it turns out that I do need to 
validate the values, but that's beside the point).
