OK, but why does the compiler accepts something like:

  Point* pp1 = &p1;
  writefln("Accessing p1 using pp1: ( %d,%d )", pp1.m_x, pp1.m_y);

I mean it seems that the leftside of "." can be either an object
reference (p1) or a pointer to an object reference (pp1). Is this
indeed the case?

BTW, I tested the above 2 statements in main(), and the result was
correct.

Anyway, I guess I have to give up using pointers to objects. (may be
it's OK in structs, not classes??)
