N3733 US-15 says:

Given the adoption of N3655, it is possible to rephrase uses of the type traits throughout and thus both simplify and clarify the text.

It goes on to propose:

Replace each occurrence of the form “cv typename typetrait<...>::type” or the form “cv typetrait<...>::type” by ”cv typetrait_t<...>”.

Marshall Clow has indicated to me that the consensus in LWG is that this change is worthwhile.

NB US-15 (C++14 CD): Use the _t form of type traits.
d33d389 
Throughout the text, replace uses of traits of the form

  typename decay<T>::type

with the shorter form

  decay_t<T>

using the alias templates introduced in the CD. Do this for all type
traits with such aliases.

Closes #178.
