Are there any examples of pretty-printing the OCaml AST from the
toplevel?
I'm looking to use this during interactive debugging.
I see the following example in the camlp4 changes doc
camlp4 -parser OCaml -printer OCamlr foo.ml
but I'm still browsing through Camlp4.ml to figure out what that does
exactly.
Thanks, Joel

Camlp4.ml is a generated file. It's perhaps not the best way to read camlp4
sources.
