and, as someone pointed out, this does work:
$x = ['abc','def','ghi'];
print @$x[2]."\n"; # prints 'ghi'
but i couldn't tell you how perl reads this, except to say that '@$x'
dereferences and then '[2]' gets the array element.
but i don't know why a '$' isn't needed to tell perl you want the scalar
value of that element.
