Here's what a typical gate class definition looks like:
 
```cxx
#include <pqxx/internal/callgate.hxx>
 
namespace pqxx::internal::gate
{
class PQXX_PRIVATE @gateclass@ final : callgate<@host@>
{
  friend class @client@;
 
  explicit constexpr @gateclass@(reference x) noexcept : super(x) {}
 
  // Methods here.  Use home() to access the host-class object.
};
} // namespace pqxx::internal::gate
```
*/

template<typename HOME> class PQXX_PRIVATE callgate

protected:
  using super = callgate<HOME>;
  using reference = HOME &;
 
  explicit constexpr callgate(reference x) noexcept : m_home(x) {}
 
  [[nodiscard]] constexpr reference home() const noexcept { return m_home; }
