It's becoming obvious that metadata is desired for many of the reference types. It exists for Vars, and has been requested for namespaces and fns, and would be useful on Refs and Agents too. Doing this soundly will require a new variant of with-meta for reference types (destructive, atomic, alter-meta), and a rejiggering of the IObj interface hierarchy, splitting the metadata reading from the writing, so all metadata can still be accessed with meta and ^. It will also have to be understood that metadata will be for fn closures only, not IFns in general, as things like maps are already both IFn and IObj.
