It's not clear how much boost.org magic they used. Failing that, a GCC extension could be needful. From the ref: --- Conclusion We attempted to represent ownership and borrowing through the C++ type system, however the language does not lend itself to this. Thus memory safety in C++ would need to be achieved through runtime checks. Example code #include <type_traits> #include <utility> #include <assert.h> #include <stddef.h>
