Re: alias this doesn't work for properties.

adding refs to the returns of the getters allows the code to 
work but only getters are called(hence the need for refs).

Please allow alias this to work with overloaded functions. 
(specifically properties, b.Y = 3; is not b.Y() = 3 but b.Y(3);)

b.Y = 3 is rewritten as b.Y(3)

You are asking for an "int" to be be implicitly convertable to an 
"A", which isn't possible.
