--- Comment #1 from Walter Bright <bugzilla at digitalmars.com> ---
In C++:

  struct S {  ~S(); };
  union U  { S s; };

g++ -c foo.cpp
foo.cpp:2:14: error: member 'S U::s' with destructor not allowed in union
 union U  { S s; };
              ^
foo.cpp:2:14: note: unrestricted unions only available with -std=c++11 or
-std=gnu++11


What was C++11's rationale?
