if I have a class X, and a constructor X(X&) defined, and abc is an
instance of X,then
  X a = abc
works as described in the book.
However, if I have abc and def as instances of X, and operator + defined
as: X& operator+(X&, X&), then the following:
  X a = abc + def
does not call the constructor when creating a (I get bitwise copy of result).
Is this behavior correct?
