Here's an interesting C++ statement.  What does it mean?

    int &const r;

Hopefully your answer is that it is illegal and/or meaningless.  If
so, look in ARM 8.2.2 [References], which states:

    In a declaration T D where D has the form

        & cv-qualifier-list-opt D1

    the type of the contained identifier is "... cv-qualifier-list
    reference to T."

And, of course, a cv-qualifier can be const or volatile.  

What is a const reference??!?  Is this an error in the ARM, or have I
totally misunderstood references?
