Well, sometimes it is useful to be able to poke at memory directly.
For example, changing the sign of a floating point value is much faster
by flipping that one bit at the end of it than doing it with the FPU.
(Of course after this little trick your program will assume IEEE floating
point numbers. But for many purposes that suffices.)
