zshparam(1):
Array Subscripts
Individual elements of an array may be selected using a subscript.
A subscript of the form `[exp]' selects the single element exp, where
exp is an arithmetic expression which will be subject to arith‐ metic
expansion as if it were surrounded by `$((...))'. The elements are
numbered beginning with 1, unless the KSH_ARRAYS option is set in
which case they are numbered from zero.
