That's precisely why I would favour using the same template syntax
for argument and local variable (and function return) type deduction-
they are all equivalent.


template<typename R, typename A, typename L>
R func(A a)
   const L& x = exp;

instead of

template<typename A>
auto func(A a)
   const auto& x = exp;
