If you wish to easily use a simple ownership ptr and do not worry bypassing
some "mutable usage rules", you could always try the good old non standard
mutable_ptr<>:

http://groups.yahoo.com/group/boost/files/ptr/mutable_ptr.hpp

[...]

Some algorithms may not work portably at run-time but simple ones will, this
will depend on your project needs.  But it is always possible to convert
the list< mutable_ptr<X> > -> list<X *> before doing so.
