 From the DIP:

The copy constructor declaration will be recognized by the parser when the tokens @, implicit, this are encountered exactly in this order

Regarding "exactly in this order". The code below would be allowed and define copy c'tor for `A` and usual c'tor for `B` ?

     struct implicit{}

     struct A {
         @safe @implicit this(ref A) {}
     }

     struct B {
         @implicit @safe this(ref B) {}
     }

We'll change that part to accept the standard attribute syntax.
