Prior to this DIP, one might have defined:

this(ref S a, int b=0) {}

This function is called only explicitly, but after this DIP, it 
will get called whenever a S instance will be copied. If you are 
against this function being a copy constructor, I can understand 
that, but C++ is considering it a copy constructor and for this 
first iteration, we are too.
