I don't think the ability to easily index sequences from the right is
in dispute. Just the fact that negative numbers on their own provide
this functionality.

Because I sometimes find it usefull to have a sequence start and
end at arbitrary indexes, I have written a table class. So I
can have a table that is indexed from e.g. -4 to +6. So how am
I supposed to easily get at that last value?
