the "Named Variable Lib" is a lightweight macro & template library which allows you to write:

This looks equivalent to the Name-Value Pair implemented as part of the serialization library already accepted into boost. It not documented separately as other candidates for separate boost components are - maybe it should have been. I don't see this as a problem. The one in the serialization library only has the functionality required to support serialization and I have often expressed the desire that appropriate pieces be moved out of the serialization library and into boost generally - along with the responsibilities of maintenance, documentation, testing, etc. So please look at the serialization library one and see if you can reconcile all of this.
