Consider specfun states to have a separate param type that would have the (true) Wronskian?

Would it be a good idea for specfun states to have a separate param type that would have the (true) wronskian?

[emsr]

So we would have, say,

template<typename _Tp>
  struct __cyl_bessel_t
  {
    struct param_type
    {
      _Tp __nu;
      _Tp __z;
      // Return true Wronskian for the cylindrical Bessel functions.
      _Tp __wronskian() const;
    };
    _Tp _J_value;
    _Tp _J_deriv;
    _Tp _N_value;
    _Tp _N_deriv;
    // Return Wronskian of the obtained solutions.
    _Tp __wronskian();
  };

I think I like this.
