in thread (OT) Interview questions -- your response?

@array[0..$#array] = @array[reverse 0..$#array]; That's *not* a built-in array-reversal method.
Nor it it an "in-place" reversing method, failing the requirements of the question. You've made an entire copy of the array in a different part of memory.

    True enough, and not an unexpected claim. Though one *could* argue that:
    @array[$left,$right] = @array[$right,$left];

    Isn't any more "in-place", as it is the same thing when the array is only two elements. And I didn't see where using a constant amount of additional memory was part of the requirement :-)
