Come on, Parsetree.structure->Parsetree.structure does not solve the 
scope rule problem.
It's essentially a less powerful p4 tool and does not solve the problem 
at all. It just fragment the community again.

For one thing by preventing the extension of OCaml's concrete syntax and making attributes part of it, using them doesn't break other tools that act on OCaml sources files; the first one being your syntax highlighter.
