$a discards the empty elements in the "a" array. Use "${a[@]}"
instead.

$* in zsh also discards the empty elements (it's even worse in
compatibility mode with other shells where word splitting and
filename generation may also be done). Use "$@" instead. Or
better, write it "for i do".

Except that it doesn't work for arrays. You'd need to  use eval
here.
