Probably we should add some type trait utilities to get corresponding complex and real types, something like (I'm trying to avoid the macro `complex`):
```
template <typename T> struct make_complex;
template <> struct make_complex<float> { using type = float; };
...
template<typename T> using make_complex_t<T> = typename make_complex<T>::type;
...
```
and define `make_real` similarly.  WDYT?
