There is a hack in caml_call_gen functions to make Js.wrap_callback work even when the OCaml function is called with more arguments that it expects. This hack was missing in the double translation case.
Also, fix function arity computation for
Js.Unsafe.meth_callback
andJs.Unsafe.callback
.We should probably run the whole test suite with
--enable double-translation
, not just the effect tests. (I have run it manually.)
