--- Comment #1 from Jonathan Wakely <redi at gcc dot gnu.org> --- I don't see any benefit to this warning. What harm does the example code do? Has anybody ever been confused about the semantics, and expected the cv-qualifiers to have an effect? If this language feature doesn't lead to confusion or mistaken code, why should there be a warning?
