Oh @Sirraide , I forgot to mention - the extra state I added to `APValue` is more than a counter; there's also a `QualType` because we otherwise can't distinguish between e.g., "a reflection of an int value" and "a reflection of a short value" (since an `Int`-kind `APValue` isn't, IIUC, sufficiently strongly typed). Assuming there's no clever way around needing that, that might further motivate the approach I outlined above.
