Another try to describe the problem:
When I get a delegate, I'd like to use it unless it become invalid.
How does using an object solve that ?
Unless this is a struct-member delegate (which is not often used
anyway and can be marked as dangerous e.g.):
---
T delegate(A) del = ...;
rt_attachDisposeEvent(_d_toObject(del.ptr), &onDelegateDisposed);
---
I still see many possibilities without changing the language. For
instance, allowing to attach dispose event to something else than an
object.
Thus making that "something else" almost class but not class and I don't
see why not just use class instead of creating a new entity.
