Sorry, I don't understand the question...

but $foo[x] (i.e. $alltimes[0]) is a single element of an array; a scalar
variable.

@foo[x] is a different beastie (an array slice) and will generate a warning
under -w

    Scalar value @foo[0] better written as $foo[0].

_Most_ of the time, if someone writes @foo[x], it's a mistake... (hence the
warning)
