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.
