I'd like to maintain a unique set of symbols or ints and insert/remove them from a list. It would work like Zl Reg or bag, except that I could use symbols.

It should support having nothing in the set, so that when it's empty you can still get a bang to know it's empty.

Basically like the data structure "set" in C++

I've searched around... Lobjects, etc, and I see nothing like this at all. Seems like a very simple requirement.

So if the contents of the list are:
Foo Bar Baz

set-of-symbols

It should work exactly like Peter Elsea's Lbag, except with support for symbols. Lbag has the proper right side outlet for bang if the list is empty.

coll can be your friend here, with a little work:

Will the use of iter cause the results to happen in another interrupt-- or will everything complete in exactly one message event?

Since you mention "set" and C++, are you a programmer? Whenever I need a data structure that Max doesn't support out-of-the-box I whip something up in a Java external. For object-oriented & data structure stuff this is a lot easier than patching IMO. Then you are in a good position to add all sorts of functionality later that would be difficult in a patch.

It would be easy to make a Max external wrap one of Java's Set classes (like 

http://java.sun.com/j2se/1.5.0/docs/api/java/util/HashSet.html)

 to do everything you need. If you are interested in going this route, I could post a Set external later. With source code so you can customize it if needed. Let me know...
