I can remember the time(s) when I had forgotten enough about Emacs
Lisp that I wanted to ask this question.  I always checked myself in
time and found the answer, but I think this is (a little bit of)
evidence that TFM needs a simple improvement.

Just put "STRINGS ARE ARRAYS" in big fat font at the beginning of the
Strings section (which precedes the Sequences Arrays Vectors section).
