Version 3.0: major API changes.

  • rope-fold/leaves does not automatically unbox the leaf structure.
  • added rope-depth, rope-append*, rope=?, rope->vector, vector->rope functions.
  • rope:concat has an additional field 'depth'.
  • rope-append automatically rebalances a rope if it is too deep.
