Moreover, 'end' and 'length' correspond only in the case of _zero-based_ 
arrays.  If you create a class that implements 10-based arrays, you'll more 
likely want this notation for the end of the array than for the element 
that's 10 away from the end.

You could even invent signed-index arrays - maybe there's a use for indexes 
ranging from -16 to 15 inclusive, IWC -$ would signify the beginning.
