I thought about following the C++ dynamic casting style, so out_cast(), but that seemed a bit pejorative. What about outer_cast()? > FWIW, I like the from_ part of the original naming, as it has some > clues as to what is being done here.

I'm not opposed to container_from() but it seems a little less descriptive than outer_cast() but I don't really care. I always have to look up container_of() when I'm using it so this would just be another macro of that type ...
