Why does C++11 have a make_shared template, but not a make_unique template?

This makes code very inconsistent.

auto x = make_shared<string>("abc"); auto y = unique_ptr<string>(new string("abc")); 

Answer 1

According to Herb Sutter in this article it was "partly an oversight". The article contains a nice implementation, and makes a strong case for using it:

template<typename T, typename ...Args> std::unique_ptr<T> make_unique( Args&& ...args ) {     return std::unique_ptr<T>( new T( std::forward<Args>(args)... ) ); } 

Update: The original update has been updated and the emphasis has changed.
