I've always used the named branches feature of mercurial to work with branches, and I'm quite happy with it. I've read about the bookmarks fature of mercurial, although haven't used it yet. The only reason for using bookmarks that I can see is if one prefers the git-style branching model, which I don't.

So, are there use cases for mixing named branches and bookmarks for the same repository?
Does it even make sense?
