2) You're right. I had for= gotten that class template arguments are not being deducted - even when we = just are calling the constructor

If I understood you correctly, you = mean to transfrom int : fib(int n) {/*blablabla/*} to fib_class f= ib(int n) {return fib_class(n);} , when fib_class is some unname= d data structure.
 Yes

auto coro=3Dfib(10);
auto iter=3Dfib.begin(= );
`fib` is a function. And as I said, if you want to = adapt a coroutine to a range, just use something that's generic to all kind= s of functions.

= ++iter; //what does this mean? what is the value of *iter now?
`++it` should be a no-op (which is totally allowed by the standard= ).
