Should it not be in shared_ptr serialize method?  The type is

list<shared_ptr<const T> >

You get the same problem with

shared_ptr<const T>

which can't be written.  So if you have a member e.g.

shared_ptr<const MyClass_c> m_MyClass;

The the actual member isn't const, it is a shared_ptr, but the thing it 
points to is a const object so shouldn't shared_ptr serialize do a 
const_cast on its underlying pointer?

If it were a

const shared_ptr<T>

then I agree that it should be in serialize/list.hpp (or probably an 
base header of this as the actual serialization doesn't seem to be done 
there)

Thanks
