Hi!

Converting all the ifnet dereferencing and converting it to accessor
functions/macros seems like a no-brainer pass. You can do this without
necessarily converting them to void *. That can be a separate pass.

i wonder about the immediate benefits of making it fully opaque versus
"mostly opaque-ready for you." Would we get less formalish checking
coverage with static analysis tools and the compiler?
