When you list the current ways to achieve class deletion, = in the static_assert example you state:

  1. code to indicate a class= is not to be substantiated should be part of the
  2.      = ;           header, not the body of the definition= ..

yet later you say that 

=
class A =3D delete; 
class A =3D delete;

would be ODR violation, so practically you still can't del= ete the class in the header.  I think this restriction should be lifte= d, so that multiple "definitions" of deleted classes would be possible (but= still disallow a normal definition of a deleted class).
