Since traffic seems to have slowed on this list, I'd like to again ask what changes are left to be made. As discussed in an earlier subthread, I think that any statements about indexer time-complexity should be removed or moved to an "implementation notes" section. Indexers are no longer used in the description of ranges, and are not mentioned in the SRFI document outside of the `range' constructor, where the indexer procedure is caller-supplied. -- Wolfgang Corcoran-Mathe <xxxxxx@sigwinch.xyz> "I have discovered a truly marvelous implementation of this function which this 80-column limit is too narrow to contain." --fishythefish
