Sorry, no.
//C++
A* get(unsigned int id);
//D
A get(unsigned int id);
Those are the equivalent declarations. A reference is, for these
intents and purposes, a pointer and D classes are reference
types. In D, "get" returns a reference to an object, i.e. a
pointer to an object.
C++ does not have polymorphic pointers to pointers to class
objects, for good reason (see my original reply). AFAIK the same
reasons apply to D, hence D has no polymorphic pointers to
references to class objects.
