This is a feature that works with all pointers to a sequence of
items, like in C. But array bounds are not verified, so it's more
bug-prone. So if you know the length it's better to slice the
pointer as soon as possible, and then use the slice:
auto ap = pp[0 .. N];
writefln("%s", ap[0].text);
Or just:
printf("%s\n", ap[0]);
