Question
Does "Fred& const x" make any sense?
Answers
No, it is nonsense.

To find out what the above declaration means, you have to read it right-to-left. Thus "Fred& const x" means "x is a const reference to a Fred". But that is redundant, since references are always const. You can't reseat a reference. Never. With or without the const.

In other words, "Fred& const x" is functionally equivalent to "Fred& x". Since you're gaining nothing by adding the const after the &, you shouldn't add it since it will confuse people. I.e., the const will make some people think that the Fred is const, as if you had said "const Fred& x".   Your Comment
