You should be able to look things up from a key or iterate over the list of elements in key order. Look at the MFC for their Map class and you'll see that I didn't exactly invent it. :-) > I also think that a linked list with an "insert into the right place" > and a "sort this whole list" would probably suffice to satisfy both > sorted and unsorted lists.

I want a kind of a list I can use to just pile up a bunch of things and get them back later in no particular order. (The ability to create stacks and queues, basically.) I also want a kind of a list I can hand things to and say "You store this any way you like - but I'll be expecting to scan over them in sorted order..." and/or "Heres a bunch of things to store. Now - go be a good little list and sort them for me." You can clearly build both kinds of lists into a one-size-fits-all package, but I think it might be better to separate out ordered vs unordered things because I don't want to have to do any extra work just to pile up unordered things. However, if a one-size-fits-all package is the way it eventually ends up (and possibly with lots of smart creative people figuring out how to not impose extra work where it isn't needed) I wouldn't likely run off to C++ in disgust.
