Fair enough; I think I'm describing the horizontal bar of the "T" and you're pointing out the vertical, and we differ on the amount of fragmentation ergolib represents. (Despite not using CL on the daily, upon perusing ergolib's source I found it a relatively straightforward mod-con library, so I don't think it necessarily fragments)
(But I was pretty serious about that list: I would hope a programmer just out of school would have heard of all of them, and expect anyone experienced to have done most of them, if not necessarily in the languages that make each one easy. Similarly, from Heinlein's original list, I currently lack only practical experience in planning invasions [though I have theoretic hex-board experience], butchering hogs [though I have a friend who has offered to teach me], and dying gallantly [though I have "I am just going outside and may be some time" as an example to follow should the occasion arise])
