introducing scoped do expressions with a specific do return to leave their scope.

Example from the paper:

auto a = do {     if (cond) {         do return 1;     } else {         do return 2;     } };   This would give another option for escaping nested scopes.

You can use a lambda at the appropriate position instead.

 

[&] {

    for (int i = 0; i < x: i++) {

        for (int j = 0; j < y; j++) {

            for (int k = 0; k < z; k++) {

                if (something)

                    return;

            }

       }

   }

}();
