To declare a function deprecated you could either just give the traverser-tool a list of deprecated functions, or use a hack to embed the annotation as valid OCaml source code (not what I would choose): deprecate.mli type 'a t = 'a in your code: let f = ... in ignore (f : _ Deprecate.t); I'm not sure we want to integrate this ad-hoc feature directly in the language itself -- I'd rather wait until someone comes with a decent pragmas/annotations proposal. In the meantime I think a bin-annot-based tool could suit your needs.
