Parsing mistake leads to warnings

[Kamikaze Dominic Fandrey]

I'm getting warnings for a namespace member that doesn't exist:

/usr/home/kamikaze/stark/Yggdrasil/src/units/Units.hpp:801: warning: Member rhs (variable) of namespace units is not documented.
[ … warnings from not yet documented code ]
/usr/home/kamikaze/stark/Yggdrasil/src/units/Units.hpp:801: warning: Member rhs (variable) of namespace units is not documented.
<rhs>:1: warning: parameters of member units::rhs are not (all) documented

The following code leads to this:

namespace units {
[ … ]

/**
 * Binary operator to divide a scalar value by a unit typed value.
 *
 * @tparam T
 *      The scalar type
 * @tparam Spec
 *      The dimensions and factors characterising the unit type
 * @param lhs
 *      The scalar value
 * @param rhs
 *      The unit typed value
 * @return
 *      The quotient with a type derived from the rhs value
 */
template <typename T, class... Spec>
constexpr auto operator / (T const lhs, units_t<T, Spec...> const rhs)
-> decltype(typename decltype(rhs)::scalar{lhs} / rhs) {
        return typename decltype(rhs)::scalar{lhs} / rhs;
}

} /* namespace units */

The problem seems to be with the decltype() expression. The following documentation is created for the bogus member:

Variable Documentation
units::rhs
Initial value:
{
return typename decltype(rhs)::scalar{lhs} / rhs
