[Compiling error] void_t is a c++17 feature.

[fionser]

The std:void_t is a c++17 feature, should create some macro to cast down to c++14 compiler.

For example

template<typename... Ts> struct make_void { typedef void type;};
template<typename... Ts> using void_t = typename make_void<Ts...>::type;

Thanks for bringing this up! It will be fixed in 3.5.4.
