Per the official language terminolgy, int is a dynamic array regardless of
what it's a slice of. And aside from lifetime issues, there really isn't a
semantic difference between a dynamic array that's a slice of GC-allocated
memory or a slice of something else (like a static array). It acts exactly
the same, including the abilility to be appended to (it's just that if it's
not GC-allocated, it's guaranteed to not be able to grow in place, whereas
with a GC-allocated array, it might be able to).
