I wouldn't consider embedded systems to be the most common kind of C
coding out there, particularly when people compare against C++ (I
don't remember ever hearing of anyone doing embedded work in C++,
though I'm sure it does happen). Nevertheless, you're exactly right
about the typedefs. Writing crazily complicated type declarations
without typedefs is like writing massively nested list comprehensions
without intermediate variables. Hey look, Python's terrible! Or maybe
they're just non-idiomatic examples.
