How to create std::array with initialization list without providing size directly

How can I make a3 compile?

int main()
{
    int a1[] = { 1, 2, 3 };
    std::array<int, 3> a2 = { 1, 2, 3 };
    std::array<int> a3 = { 1, 2, 3 };
}

It's very inconvenient, and brittle, to hard-code the size of the array when using an initialization list, especially long ones. Is there any work around? I hope so otherwise I'm disappointed because I hate C arrays and std::array is supposed to be their replacement.
