A container of clone_ptr is a more elegant solution if you can't use move semantics, since it actually has the right ones. You may want to implement it using COW however since non move-aware containers can do a lot of spurious copies.
By the way, there is a cloning pointer included in the generic_ptr library I've been working on recently: https://svn.boost.org/trac/boost/browser/sandbox/fmhess/boost/generic_ptr Still no docs, but at least I'm starting to add some tests. It should also be possible (haven't actually tried it yet) to combine the cloning pointer it with a shared pointer, like generic_ptr::cloning<generic_ptr::shared<T*> > to support a combination of deep and shallow copy handles, although you'd have to pass the cloning a null deleter to prevent it from double-deleting the owned object. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (GNU/Linux) iEYEARECAAYFAkpzSW0ACgkQ5vihyNWuA4U8rgCdHtMpaV/kEl9Z58iVwrw+c42y hwUAoJwb40mJHfAobIUV5MD/nARe8DWA =OF/7 -----END PGP SIGNATURE-----
