I know very well about the "didactical lies" in the TeXbook,
I have adopted the idea in my own work, and I have
defended it when I have been criticized for it.
The TeXbook is a brilliant "guide" to TeX that is very difficult
to top. It leads to understanding considerations that
a user hasn't dreamt of before. However, after attending
such a course, you may be unable to remember all the
details -- and indeed the course may not have presented
all of them. Now, where can you find them -- in a few minutes?
(So please recognize the difference between "lying"
[for a didactical reason] and telling nothing at all!)
