Damn, on re-read, I notice, that my own implementation of
Map.Entry could just hold a ref to the map and implement
setValue() to write the value back into the Map...

Maybe, even, the HashMap's entrySet()'s items even do that
for the Map-"backing". - I know, I could look into src.zip,
but probably won't.
