TransformationTrait Alias void_t

by Walter Brown

Excerpt:

This paper proposes a new TransformationTrait alias, void_t, for the C++ Standard Library. The trait has previously been described as an implementation detail toward enhanced versions of two other C++11 standard library components. Its value thus proven, void_t’s standardization has been requested by several noted C++ library experts, among others.
