Please file a bug on http://d.puremagic.com/issues/ The example doesn't even compile: Error: cannot implicitly convert expression (this) of type S to S* > 2. The return value of opAssign is `S*`, so it would seem that `t` is > assigned a pointer value? The correct information is: t=s is defined to be semantically equivalent to: t.opAssign(s) which means a signature of just void opAssign(ref const S rhs) { //... } > 3. What is `tmp`, just another stack allocated instance of S? I think it is just an example of something you might do. > 4. What is the syntax for explicitly calling the destructor?
