Sorry, I'm a bit inaccurate here: The assignment expression in `PutX` is not ill-formed but would expand to a recursive call to `PutX` since we're assigning to the member with the very setter. (Of course, this would end up crashing if we [run the program](https://gcc.godbolt.org/z/e3fW3W73a).)

I think I was suggesting that this is a bad case for supporting such an extension: the assignment expression could be of a syntactic form with an inappropriate hint location though.
