Yes, and it is one the simplest common cases. The correspnding formulation in C++ would be as simple as well, e.g. (auto x, auto y) { x + y; } (three months ago, Bjarne showed another candidate: { x, y; | x + y; }) The main issue in this discussion, however, concerns what to do when a reference is made to an automatic variable in an enclosing scope. -- Gaby
