Hmm, I think there’s some logic to having a warning anyway. If a parameter is taken by reference,
then it’s presumably going to be modified. So if you pass something that isn’t a variable (and
therefore the modified result can’t be accessed) to a by-reference parameter, it doesn’t really
make sense.
