I get that, now, but thanks. What I really want, though, is to have a method in the system named something starting with 'slice,' because that's what I (and most of my friends, really,) would look for when trying to do the thing I was trying to do when I couldn't find a method that did what I wanted to do. When I think about grabbing a subset of a SequenceableCollection, I don't think to use the word 'copy' to find what I'm looking for.
