Using this is a good idea, but I don't think we should automatically ref  
the value.  Also this is already a symbol name, can't we just use it?   
What I think might be a good idea is to *name* the target this, and then  
just allow the normal adornments to describe the type.  i.e.:

@property int set(ref int this, int y) {}

will work only for lvalues, whereas

@property int set(int this, int y) {}

works for rvalues also.  The

What do you think?
