I'm sorry but I did not introduce this. Since declval is not constexpr
I explicitly did not do the above (gcc also complains) but this:
static const int value = ((const typename
std::decay<T>::type*)(nullptr))->size();
I suppose this also didn't compile for you. What's the error message?
Best,
Carsten
