example usage with dune

[nrolland]

it would be helpful to have a sample project using dune to play with

naively pasting the example I had some error with non-interactive code

Error: The type of this expression, (_[> Binop of _[> Add | Div | Mul | Sub ] * 'a * 'a | Int of int ] as 'a, '_weak1) operator list list, contains type variables that cannot be generalized

which seems to indicate that some type annotation is required as in common error message

Request taken!

I've never found time to get into dune (although I wanted to), so this is a good opportunity to get familiar with it.

Hmm. This wasn't an issue in earlier versions of OCaml. I'll rework the provided example. Thanks for reporting!

It's my mistake : I did not use all of the example, and the missing part caused a pb with variant record, to which the interactive version was more lenient (hence my confusion).

here's a very simple example using dune : https://github.com/nrolland/oparser
