I think the root reason why such confusion is the bad choice that D made in the beginning, to define properties with the same syntax as functions, while properties should be rather an extensions of the variable concept, not of the functions concept.
Properties should only appear to be variables from the user's point of view. From the implementation point of view, they *are* functions. So the syntax for getting and setting property values should be the same as for variables, but for implementing them, it makes sense to use syntax that is close to the one used for functions. That way, you can avoid verbosity and the need to use implicit parameters, like what they have in C#.
Current implementation of properties in D is not perfect, but the only issue with the syntax for implementing them is that there isn't a clear distinction between setters and getters, which leads to some confusion with global properties in the presence of UFCS. But that can be solved by having @property(get) and @property(set) or @getter and @setter. No need to adopt the inferior C# approach.
