In Andrei's book, as well as in the Phobos source, there are property
getters that return refs, as in...
@property ref T front() {
return _payload[0];
}
... and code that uses this with simple assignments, such as:
r.front = foo;
For some reason, I can't get this to work in my code :-/ DMD seems to
insist that I add a setter as well (i.e., @property T front(T val) {
return _payload[0] = val; }).
On the other hand, I *do* get
r.front() = foo;
to work. That works well even without @property, of course; and r.front
fails even without @property.
Then, again, if I write both the getter (front()) and the setter
(front(T)), that works even without @property (which, then, seems
rather redundant?).
So ... I guess I have two questions:
1. What's the point of @property (when it seems I get the same
functionality without it)?
2. How can I make r.front = foo work, when I only have r.front(),
returning a ref (which seems like it is used in actual code)?
