I believe that someone did suggest using an "fd style" interface where
you are passing around a "handle" or a "cookie" rather than a pointer
to a struct/union/whatever.

However, I was just responding to the general point of typedefs being
useless, and the argument that struct could be used everywhere in place
of a typedef.  I was not advocating a particular implementation, just
noting, as others have, that there were advantages to their use.

I have never heard of another project that bans the use of typedefs
but I guess there aren't many projects like gdb.
