Well, it would save us from horribly wrong DOC strings like
quote is a special form in ‘C source code’.
(quote ARG)
Return the argument, without evaluating it. ‘(quote x)’ yields ‘x’.
Warning: ‘quote’ does not construct its return value, but just returns
the value that was pre-constructed by the Lisp reader (see info node
‘(elisp)Printed Representation’).
This means that ’(a . b) is not identical to (cons ’a ’b): the former
does not cons. Quoting should be reserved for constants that will
never be modified by side-effects, unless you like self-modifying code.
See the common pitfall in info node ‘(elisp)Rearrangement’ for an example
of unexpected results when a quoted object is modified.
[back]
Sometimes a quote is just a quote.
