no, that's not it.  #'x is read as (function x).  'x is read as (quote x).
you can easily see this by evaluating (car (read)) and typing in each form.

`lambda' is now a macro that wraps itself in a `function' form.  this means
that (lambda (x) (+ x x)) evaluates to (function (lambda (x) (+ x x))),
which is what would be read if you typed #'(lambda (x) (+ x x)), so you can
omit the #' from `lambda' forms with no visible effects in normal code.

if you think this year is "97", _you_ are not "year 2000 compliant".
