[wg-camlp4] Extension developers: we need you!

[Alain Frisch]

Now is a good time to start collecting more concrete feedback from 
extension developers on the current proposal (ppx + extension_points). 
Are there people on this list interested in porting their existing 
extensions (or other tools which can benefit from attributes)?   This 
will be greatly helpful if the current design can be validated by real 
extension developers.  Porting real extensions will also help to isolate 
a good set of "convenience" functions to build or deconstruct AST 
fragments in a light way.

(Disclaimer: there will still be some more cleanups to the Parsetree 
definition and helper modules (Ast_mapper, Ast_helper), so the code 
written now will need to be adjusted for the final version, but I expect 
those changes to be quite easy.)
