I don't know which implementations you are considering (are they 
publicly available online?), but here is one I found to perform good enough:

https://github.com/eggs-cpp/tupleware/blob/draft/include/eggs/tupleware/core.hpp#L187

Just drop the `constexpr` since it's not actually needed and it confuses 
GCC. It's a bug according to my reading of [expr.unary.noexcept]/3, but 
I didn't have the time to investigate further yet.
