I'm using the STLSOFT_METHOD_PROPERTY_GETSET macro to implement properties. 
Now, I want the setter functions to return a reference to their class, so 
that I can chain calls to setters, like:

// definition of setters in some class
class image
{
...
class_type & set_width(int width) { m_width = width; return *this; }
class_type & set_height(int height) { m_height = height; return *this; }
...
};

// use of setters
image a;
a.set_width(100).set_height(100);

But I still want the other possibility, to use the properties as such:
// use of properties
image b;
b.width = 100;
b.height = 100;

Now, the STLSOFT_METHOD_PROPERTY_GETSET macro does not like setters that 
return a reference to thieir containing class. I'm wondering what it would 
take to change the code to allow such type of setters.
