But with the same reasoning you would end up reintroducing shadow warnings
between local variables and *any* functions, not only the ones visible from a
using statement. It has been recognized that triggering a warning in such a
case was too much:
 - gcc 4.8 removed them for free functions
 - gcc 5.0 removed them for member functions
and I think that it thus make sense to remove them for member functions visible
through  "using". Did I miss something special regarding the use of "using"?
