+The following should fail saying that %{read:...} isn't allowed in this
+position, because it was indeed not supported by older versions of Dune. Due to
+improvements in the core of Dune, this is now supported. Because the error used
+to be discovered dynamically as we were trying to evaluate the dependencies,
+the new code simply doesn't detect it. We should add a proper version check for
