I’ve always viewed arrays as an infinite field of nulls. The only time this isn’t true is when
you use array_key_exists() or care about the warnings (which make it less useful, IMHO). When you
treat it as an infinite field of nulls, you get some interesting mathematical/computational
properties you can exploit. Trying to treat it as a map/indexed-array is when you start running into
weird problems.
