The This “Reference”
lWhen memory for an object is allocated, a reference to that object is created and called the “this” reference
lLike C++, it is the first implicit argument to each method
lUnlike C++, it is not a pointer but rather a reference!
•list func() {   return this; }
•Which means we do not need to dereference it
•It allows member concatenation:
•Obj.func().func().func();  //etc.
