I think I struggle to assemble a coherent notion of what it means to (conceptually) decouple a value from its type. You can completely forget the type of a value and treat it as opaque bytes, but then there are no valid operations left on the value. Even moving it around or discarding it may be invalid if it's pointed to elsewhence. The only thing you can meaningfully do is try to recover its (static or dynamic) type information from somewhere and re-‘couple’ it.
