> JEP 481 proposes Scoped Values to continue to preview in JDK 23 with one change. The type of the operation parameter of the callWhere method is changed to a new functional interface to avoid having the API throw Exception. With that change, the getWhere (and the corresponding method on Carrier) are no longer needed. The functional interface is not proposed for j.u.function at this time.

Thanks. That all looks reasonable enough, and gets us to the status quo ante + `ScopedValue.CallableOp`,  which is way better than what we have right now.
