It should be noted that at least some cases which previously required template meta programming can now be done in a more natural style with constexpr. A constexpr function can be evaluated at compile time, this means that its return value can be used in places that require a compile time constant.

constexpr functions where quite restrictive in C++11. They could pretty much only contain a single expression and a return. C++14 significantly relaxes these restrictions.

Type-level meta programming is still confined to using templates though...
