I introduced a bug in ppx_deriving.make when working on #281 and inadvertently changed the ordering of the arguments of the generated function.
The test suite failed to pick it up because the signature was also generated with [@@deriving make] and the ordering was swapped in both the signature and structure derivers.
I added a module with a handwritten signature and a derived implementation so that this can't happen again in the future.
