This is not a legal inference, and that's exactly the point Jeff made: Just because it is written in C doesn't mean people will understand it, it merely means that they will _think_ they understand it. Nontheless, we have plenty of /* You ARE supposed to understand this */ C-code already, so I don't see it as an objection to Jeff's patch. -- Poul-Henning Kamp | UNIX since Zilog Zeus 3.20 phk@FreeBSD.ORG | TCP/IP since RFC 956 FreeBSD committer | BSD since 4.3-tahoe Never attribute to malice what can adequately be explained by incompetence.
