I have moved the ''comparator'' argument back to the end of the argument list of `set-unfold` and `bag-unfold`. I'm doing this so that all unfolds will have the same first four arguments: the stop predicate, the mapper procedure, the successor procedure, and the seed. Doing this allows the creation of a generic lazy copier from any container with a for-each procedure to any other container with an unfold procedure. This will be included in a future SRFI. -- John Cowan http://www.ccil.org/~cowan cowan@xxxxxxxx Values of beeta will give rise to dom!
