Indeed, access to array elements is O(N) in zsh instead of O(1) that
one might expect. The same goes for strings, even with no_multibyte.
This makes computation-heavy code incredibly slow. If someone can fix
this, they'll have my eternal gratitude.

On the plus side zsh has fast hashtables (closed hashing with
quadratic probing). Bash's implementation is a lot slower (it's
node-based).
