For this reason, I encourage all of us to start utilising the technique of indirection for storing all primitive datatypes in our programs. Not only will this make it impossible for hackers to track our variables, it will also allow us programmers to taste the sweet taste of having stopped said hackers with a doge meme.

typedef typename Indirection<T, N-1>::type* type;
typedef typename Indirection<T, N-1>::type child_type;

{
p = new child_type;
Indirection<T, N-1>::init(*p);
}
static void cleanup(type& p)
{
Indirection<T, N-1>::cleanup(*p);
delete p;
}
};
