My point is: you do not need to convert between big and little endian, you
only have to convert between sequences of bytes and integers. You never need
even to know that integers are stored as bytes in the memory of the
computer.

In fact, I expect that you could not find access to the internal
representation of integers in OCaml, which is a good thing. Most of the
portability bugs in C come from people who have not understood the principle
of having access to the internal representation of objects (which is not to
use it :-). Alas, a lot of books about C are very i86-centered and explain
it really badly.

I think this is really exactly the same approach, and I am flattered to have
the same position af Kernighan.
