Subject: camlp4 & free variables
Date: Thu, 20 Jul 2006 01:27:06 +0200 (CEST)	[thread overview]
Message-ID: <20060720.012706.109316902.Christophe.Troestler@umh.ac.be> (raw)

Hi,

Is it possible to write a camlp4 syntax extension that "extract" the
free variables of an expression?  As an example, say I write

  FUNCTION(let z = x + 2 in x + 2 * y * x * z)

and it becomes

  fun ~x ~y -> let z = x + 2 in x + 2 * y * x * z

(of course I'd like good error reporting in case of an error in the
expression).  If it is not possible, what is the best way to build a
tool that does that (short of writing a parser for the OCaml language)?

Thanks,
ChriS
