I think that variables should be usable as components of the range (e.g. n:m).  See my other message about avoiding conflicts with {n:m}.

I also can't think of any reason to prohibit non-number first and last components (just like Range currently supports), but I think step size (if adopted as part of this proposal) would have to be numeric.
