* anyToExnInternal obj will take any value obj and wrap it * in a Js.Exn.Error if given value is not an exn already. If * obj is an exn, it will return obj without any changes. * * This function is mostly useful for cases where you want to unify a type of a value * that potentially is either exn, a JS error, or any other JS value really (e.g. for * a value passed to a Promise.catch callback) * * IMPORTANT: This is an internal API and may be changed / removed any time in the future. * * 

*   switch (Js.Exn.unsafeAnyToExn("test")) {
*   | Js.Exn.Error(v) =>
*     switch (Js.Exn.message(v)) {
*     | Some(str) => Js.log("We won't end up here")
*     | None => Js.log2("We will land here: ", v)
*     }
