- a first goal is simple functions, with a single return statement (which may even often be the only statement).
After playing with it a bit, I am not sure how to use it in the simple forwarding case:
T f(int); auto g(int i){return f(i);}
If T is a reference, this does a copy.
auto&& g(int i){return f(i);}
Now if T is not a reference, this returns a reference to a destroyed temporary.
