The problem is this code in object.d:

void destroy(T)(ref T obj) if (is(T == struct))
{
    _destructRecurse(obj);
    () @trusted {
        auto buf = (cast(ubyte*) &obj)[0 .. T.sizeof];
        auto init = cast(ubyte[])typeid(T).initializer();
        if (init.ptr is null) // null ptr means initialize to 0s
            buf[] = 0;
        else
            buf[] = init[];
    } ();
}

The call to `typeid` needs to return a `TypeInfo` instance.  Is there a way to
get the initializer at compile-time without a runtime call to `typeid`?
