The problem here is that you're not undef'ing the hash you made. By using
curly brackets {}, you're making a hash- a set of variables linked with
keys. It's addressed with the symbol %. So if you wanted that script to
work, it could be done in two ways-

$a[0] = "peter";
undef @a;

$a{'1'} = "peter";
undef %a;
