I understood the point of properties to be that they could, at your discretion, be backed by a mutator and/or accessor function. Thus, when you want a "manually generated" accessor, you create it and inform the property declaration to use it instead of generating code for the accessor.

In my theoretical world, at least, the use of assignment-style accessors has nothing to do with that. After all, we're talking about proxies that forward to functions that do the accessing or mutation, right? The only issue is whether the functions are generated by the framework or provided by the client (class).
