'cause `ref T` is more generic than `T*`. think of it as "greedy matching":
compiler first tries to match `int*`, and if that
void test(T)(T* arg);
void test(T)(ref T arg);

is the second overload chosen?
Making the first one take auto ref T* lets the compiler choose
the first.
Making the second one non-ref lets the compiler give me an
ambiguity error.
