Ahem. We've been arguing about getting rid of $@%, but haven't yet!
$a[0,1,2] returns exactly $a[2], since it is a $calar context.
Perhaps you were thinking of @a[0,1,2]?
In any case, having good multi-dimensional syntax for scalar access but
not for list access is not very orthogonal.
Also, C<,> inside (scalar) square brackets is B<not> useless!
Consider e.g.
print $line[do_something_for_side_effect, $a+$b]
