All constants are variables.

===  ALL CSH USERS PLEASE NOTE  ========================

Set the variable $LOSERS to all the people that you think are losers.  This
will cause all said losers to have the variable $PEOPLE-WHO-THINK-I-AM-A-LOSER
updated in their .login file.  Should you attempt to execute a job on a
machine with poor response time and a machine on your local net is currently
populated by losers, that machine will be freed up for your job through a
cold boot process.

All parts should go together without forcing.  You must remember that the parts
you are reassembling were disassembled by you.  Therefore, if you can't get
them together again, there must be a reason.  By all means, do not use a hammer.
                -- IBM maintenance manual, 1925

All programmers are optimists.  Perhaps this modern sorcery especially attracts
those who believe in happy endings and fairy godmothers.  Perhaps the hundreds
of nitty frustrations drive away all but those who habitually focus on the end
goal.  Perhaps it is merely that computers are young, programmers are younger,
and the young are always optimists.  But however the selection process works,
the result is indisputable:  "This time it will surely run," or "I just found
the last bug."
                -- Frederick Brooks, "The Mythical Man Month"

All programmers are playwrights and all computers are lousy actors.

"... all the good computer designs are bootlegged; the formally planned
products, if they are built at all, are dogs!"

                   MIT Press, 1987

All the simple programs have been written.

===  ALL USERS PLEASE NOTE  ========================

A new system, the CIRCULATORY system, has been added.

The long-experimental CIRCULATORY system has been released to users.  The
Lisp Machine uses Type B fluid, the L machine uses Type A fluid.  When the
switch to Common Lisp occurs both machines will, of course, be Type O.
Please check fluid level by using the DIP stick which is located in the
back of VMI monitors.  Unchecked low fluid levels can cause poor paging
performance.

Bug reports now amount to an average of 12,853 per day.  Unfortunately,
this is only a small fraction [ < 1%] of the mail volume we receive.  In
order that we may more expeditiously deal with these valuable messages,
please communicate them by one of the following paths:

CAR and CDR now return extra values.

The function CAR now returns two values.  Since it has to go to the trouble
to figure out if the object is carcdr-able anyway, we figured you might as
well get both halves at once.  For example, the following code shows how to
destructure a cons (SOME-CONS) into its two slots (THE-CAR and THE-CDR):

        (MULTIPLE-VALUE-BIND (THE-CAR THE-CDR) (CAR SOME-CONS) ...)

For symmetry with CAR, CDR returns a second value which is the CAR of the
object.  In a related change, the functions MAKE-ARRAY and CONS have been
fixed so they don't allocate any storage except on the stack.  This should
hopefully help people who don't like using the garbage collector because
it cold boots the machine so often.
