msvs12 treats braces as operator()

Question

#include <iostream>

struct A
{
    void operator()(const char *)
    {
        std::cout << "void operator()(const char *)" << std::endl;
    }
};

int main(int argc, char* argv[])
{
    A a;

    a{"hi"};

    return 0;
}

msvs12 is happy with this code and I can't understand why. Is it bug or something else?

Update: I tried with msvs 2013 (v12.0.31101.0 Update 4)
