It works fine for me.

I prefer to use @array, the number of elements, rather than $#array,
the maximum subscript.  (@array - 1) == $#array, unless you muck about
with $[, which I consider a really stupid idea in general.

I think it's the visual appeal of one less special character.  Also,
"@array == 0" seems more natural to express the concept of an empty
list than "$#array == -1".
