I agree that 4127 can help you find bugs.  But I can't think of any
situation where 4511 or 4512 will help you find a bug.  If you actually try
to call an inaccesible copy constructor or assignement operator, then the
compiler (correctly) fails to compile it.

Thats why I used the word "awkward" rather than "useless" for 4127.

I'll happily be proved wrong though.
