swap_in_place still needs a reinterpret_cast too to convert from the 'char *
buf' assembled from the hypothetical TCP stream.
What bugs me is that 'buf' doesn't point to a 'T' yet. It points to a
half-baked 'T'. Only after one calls swap_in_place() is the object really a
The reinterpret_casts are valuable here because they show that the
programmer is doing a potentially dangerous thing -- changing the memory
underlying a structure in place!
