Subject: [Caml-list] pretty-printing with camlp4?

Hi,

Is it possible to use Camlp4 to write pretty printers of arbitrary
data? The signature Camlp4.Sig.Printer seems to indicate the pretty
printing facility only works with OCaml ASTs...

On the other hand, with Camlp5 it is possible to write pretty
printers for arbitrary ASTs
(see <http://pauillac.inria.fr/~ddr/camlp5/doc/html/printers.html>),
so I imagine there must be a way to do the same thing with Camlp4...

Thanks!
Nicolas
