The speed gain is usually not worth the portability loss.  If you have
to copy the data just once (as it is common with stream-oriented data
transmission), it's possible to get proper marshaling almost for free.
(There are template metaprogramming libraries which can do this for
C++.  For Ada, you'd need a little code generator.)
