Note that this of course is not "safe from element removal" in general; it is just safe when you remove any element other than the next element, whereas TAILQ_FOREACH is safe when you remove any element other than the current one. For example it would not be safe to call a callback that could potentially remove arbitrary elements. It may be clearer in this case just to expand the macro in the code so that it is more obvious what assumptions can be made.
