Unfortunately, a reference member MUST be initialized in the
initialization list of the constructor of the class of which it is a
member. This is a C++ requirement. Your solution, while it may have
logical merits, is not possible in C++.

If you try to compile the example you gave, you'll see that no
compiler accepts the syntax (aside from the fact that "this" is a
pointer and needs -> instead of the dot).
