The code below almost allows the transfer functions to work as shown in
the current documentation, unfortunately
'reversible_ptr_container::c_private()' is protected and stopping the
lines 'from.c_private(). ...' from compiling. If c_private is made
public then the transfer functions work correctly, possibly there's a
further work-around?
