Hmm... a bit of a touch up (btw unbound can be represented by it's own object, 
so no special syntax required):

  r = 0<..<43
  r = 0<..<=42
  r = 0<=..<43
  r = 0<=..<=42

  r = 0<..+<42
  r = 0<..+<=42
  r = 0<=..+<42
  r = 0<=..+<=42

Basically tie-fighter ranges ( and x-wing ranges ;)  F'ugly! :( Alhtough I 
like your direction. Alternative is just to use standard-like notation:

  0 < r < 43
  0 < r <= 42
  0 <= r < 43
  0 <= r <= 42

  0 < r +< 43
  0 < r +<= 42
  0 <= r +< 43
  0 <= r +<= 42

Who said assignment always had to be 'r =' ? Of course it would be nice if we 
could just do like:

  r = :(0,43)
  r = :(0,42]
  r = :[0,43)
  r = :[0,42]

  r = :(0:43)
  r = :(0:42]
  r = :[0:43)
  r = :[0:42]
