It's not about problems in execution, it's about expression.
[EMAIL PROTECTED] returns the *number of elements*, not the index of the last
element plus one. It should not be used for index math.
There are cases where we should write @foo.last + 1, even though the
result will in almost all cases be the same as [EMAIL PROTECTED], and there are
cases where we should write @foo - 1, even though the result will be the
same as that of @foo.last.
That almost all arrays range from 0..i is no reason to write bad code.

That should be ^(@foo.last + 1), or not using ^ at all. I'd prefer the
latter.
