Yes, in my opinion it's better than the alternatives. In the end here what I will use in normal code is the basic strategy of using just comments.


>Documentation tools need to be aware of this.

D uses ddoc, as basic solution for this.


>Requires compiler patch.

As any solution that changes the language, yes.


> You need to educate this to new users etc.

I think it's not hard to understand and remember.


>Did I already mention it increases the complexity of a language that is already fighting featuritis.<

But it also simplifies code, makes it a bit safer, avoiding some possible bugs both of the original problem and created by the alternative solutions.
In the end I think this feature it's not worth it because it's a solution to a very specific problem (but this is also true for few other features of D2 that I think can be removed).
