configuration data from a file, it will be read twice.  And of course, part
of the convenience of shared_ptr is that it often makes it practical for
classes to be noncopyable, which can save development time, depending on the
nature of the class.

Here is a draft version of what could remove copy constructors usages.  It
would require proper initialization from the user in this example.  Besides
the implicit reinterpret_cast<> in the constructor which shouldn't be there
IMO, any thoughts?
