[Swift-user] last element array indexing?

Not at all answering your question but maybe giving some information that 
makes it even harder ;)

Although array indices must be integers (or perhaps numbers in general), 
there is no constraint that there are elements at any particular location. 
You can have an array containing values for f[3] and f[92]. So that has 2 
elements, and the last element has index 92. mmm.

I don't think there's much use for this 'feature', but there it is.
