Hi. I have the following two classes in my code:
```
template <class, class = void>
struct is_printable : std::false_type
{
};
/**
* @brief Type trait that indicates if class is printable.
*
* This type trait indicates that type _T_ is printable i.e. `os <<
val` is a
* valid expression (where `os` is a instance of `std::ostream` or one
of it's
* subclasses and `val` is a instance of _T_).
*/
template <class T>
struct is_printable<
T,
std::void_t<decltype(std::declval<std::ostream>() << std::declval<T>())>>
: std::true_type
{
};
```
When I try to write `@ref is_printable` somewhere else in the
documentation, the link points to the first class that contains no
documentation. I want to link to the second class. But that's
complicated (and pretty impractical). I have tried @ref is_printable<T,
std::void_t<decltype(std::declval(std::ostream)() <<
std::declval(T)())>> but it picked up only the 'is_printable' part which
(again) linked to the first class. How can I link to the second class?
