Saw your post only after answering to Marcin. Thank you very much for
going into that lengths, I really appreciate.
Maybe some light is shining into my darkness. It boils down to the
difference between (quote (1 3 2)) and (list 1 3 2). `(elisp)Printed
Representation' has probably the crucical sentences:
"In other languages, an expression is text; it has no other form. In
Lisp, an expression is primarily a Lisp object and only secondarily the
text that is the objectâs read syntax."
Still have to dig around more on this road; I would lie if I claim it's
all clear now ...
