- change : all objects are by default stored now by reference, not by copy any more. Unless the trait force_copy_in_expr is true. - rvalue refs are moved into the tree - simplifies a lot the writing of lazy method, objects. - added a macro for methods - tests ok. Further check needed to control absence of copies... - improved documentation
