Why is there no std::make_unique function template in the standard C++11 library? I find
std::unique_ptr<SomeUserDefinedType> p(new SomeUserDefinedType(1, 2, 3));
a bit verbose. Wouldn’t the following be much nicer?
auto p = std::make_unique<SomeUserDefinedType>(1, 2, 3);
This hides the new nicely and only mentions the type once.
Anyway, here is my attempt at an implementation of make_unique:
template<typename T, typename... Args>
std::unique_ptr<T> make_unique(Args&&... args)
{
return std::unique_ptr<T>(new T(std::forward<Args>(args)...));
}
It took me quite a while to get the std::forward stuff to compile, but I’m not sure if it’s correct. Is it? What exactly does std::forward<Args>(args)... mean? What does the compiler make of that?
