Initialize C++ std::array without length [duplicate]

This question already has an answer here:

• How to emulate C array initialization “int arr[] = { e1, e2, e3, … }” behaviour with std::array? 11 answers

If a std::array is defined I need to write something like this

std::array<int,3> my_array {1,5,3};

In my option this violates the DRY principle (Don't repeat yourself), since I need to specify the length of the array explicitly and it need to corresponds to the length of the initializer list.

Is there a way to write something like

std::array<int> my_array {1,5,3};

and the constant length of the array is deduced form the length of the initializer list?
