Reduced C++ code seems to be:

template <int __v> struct integral_constant {
  static constexpr int value = __v;
};
template <typename> constexpr long find_index() { return 1; }
template <typename... Ts>
using find_index_checked = integral_constant<find_index<Ts...>()>;
template <typename> class Trans_NS_mpark_variant {};
template <long, typename... Ts> void get(Trans_NS_mpark_variant<Ts...>);
template <typename... Ts> void get(Trans_NS_mpark_variant<Ts...> v) {
  get<find_index_checked<Ts...>::value>(v);
}
void TestBody() {
  Trans_NS_mpark_variant<float> w;
  get(w);
}
