Missing *-copy is an oversight, and will be corrected. It makes sense to have the full range of copy operators, so code could still be collection agnostic and yet clone a collection. I don't see any advantage to having the full set of fold operators though, except for the (weak) argument of a performance improvement in dispatch when using the collection specific folder. As for comparison, it seems that just adding some language defining equal? over the collections would be sufficient. This would leave the collections free to define equality for the values and the ordering they contain. On the other hand, this would make a portable implementation more difficult. Scott --
