Thanks. It is the same issue. Not a show stopper though since a simple `if`
fixes it.

Indeed but in that case, don't you think Json.Decode.succeed and
Json.Decode.fail must be updated to point that out? When you do `oneOf`
with `succeed` in it, you naturally expect it to work as that is what the
documentation says.
