Yes this is very confusing. I have added another section to my
wiki article (http://maxima.sourceforge.net/wiki/index.php/LexicalLayer)
which discusses the behaviour of arrays versus lists passed as an argument
to a function. Briefly (using identical syntax) array elements seem to
be passed by value
and list elements by reference. While I now understand this can be
explained somewhat rationally it is still needlessly confusing, and
different
from what people will expect (except perhaps for people with an indepth
knowledge of lisp).
