Match properties as member variables

 From client perspective, properties look like member variables.
With (auto) ref, a generic function can catch a member variable 
and read it and update it:

void swap(T)(ref T a, ref T b) {...}

The client can use swap with member variables.
But he can't use this swap with class properties - they're 
special.

Since the properties "look like" member variables, I think it is 
a valid use-case for us to want to be able to write generic code 
that can handle properties passed as arguments in the same way as 
member variables passed as arguments.

Can you write version of swap, which works also with properties 
and/or combination of properties and references?
