**Note**: The example only works because the memory is initialized to zero
(``alloc0`` instead of ``alloc`` does this): ``d.s`` is thus initialized to
``nil`` which the string assignment can handle. One needs to know low level
binary zero which the string assignment can handle. One needs to know low level
details like this when mixing garbage collected data with unmanaged memory.
