Suggestion: allow negative numbers to indicate a position counted from the

David,

This was discussed in the Working Group, but it wasn't felt that the added 
complexity was worth it; there's a strong feeling that this spec should be as 
simple as possible.

Cheers,

Understood - simplicity is a great Guiding Principle.

Might I suggest, however, using -1 instead of "-" to refer to the last item in 
an array, as this provides two benefits:

1) Allows for adding the complexity down the road in a compatible way, should 
there be need
2) Uniformity; i.e. always using integer values for referring to array elements.

Thanks for the consideration,
