 Replying to [comment:1 ramey]:

 Fixing formatting.

 I have to disagree with you here. We are not touching a const object at
 all. The shared_ptr itself is non-const.

 {{{
 T *p; // p is non-const
 T const *p; // p is still non-const
 }}}

 {{{
 shared_ptr<T> p; // p is non-const
 shared_ptr<const T> p; // p is still non-const
 }}}

 So what is the problem? I don't need a const-cast to mutate p in either
 case. This to me is a deficiency in the library not the user!
