Is the behavior you find strange (a) that ${arr[0]} is "one" or (b) that
${arr[1]} is not "two"?

If (a) you may be happy to hear that this has been changed in more recent
zsh releases, so that (without ksharrays set) ${arr [0]} is the empty
string, as with any other index that is outside the array bounds.

If (b) then this has already been explained as zsh's normal 1-based
indexing (again, without ksharrays).
