Subject: [boost] Query of Interest in annotated tree extensions to Boost.Intrusive

Hi All,

I've been working on some extensions to allow users to add annotations
to tree data structures (explanation of the idea here:

This isn't a new library submission, but it's a fairly substantial
modification to Boost.Intrusive, so I've got the following questions on
my mind:

1. Is there interest in having such functionality in boost?
2. If so, should the changes go through the formal review process?

Regarding the level of interest:
To the best of my knowledge, no one has yet released a library that
provides this functionality. I have, however, come across a few things
that indicate that the technique is in use: (Evidence of demand for such a library) (A binary tree with a 'pixel height' annotation) (A node-count annotation on B-trees) (Paper about a "count" annotation on suffix trees) (About the usefulness of annotations. Separates
the data from annotations, unlike the proposed library)

Many thanks,

Jeff Snyder
