Subject: [Caml-list] OCaml code style and syntax checking

I have a need to make automated stylistic and syntax checks to
a large amount of OCaml code.  The sort of rules would be:

 - Check that indentation is used, and used consistently.

 - Excessive use of parentheses where not needed.

 - Use ( .. ) instead of begin .. end.

 - Flag uses of various Obj.* and unsafe_* functions.

It seems to me that some of these could be tested with either camlp4
or ppx.  I think if we allowed the checker to go back to the original
code (eg to see if the parser parsed as block as '(' or 'begin'),
it might be able to check all of these things.

Anyway, before I start on it I'm wondering if anyone has ever
looked at doing this kind of thing?

Rich.
