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.

Hmm, not sure off the top of my head. Let me think on it a day or so. :-)

I'm going to release STLSoft 1.8.4 in the next day or so, and this 
will _not_ be in there, but I will look at it as soon as that 
release is done.
