T = NIL

This is a joke, right?  On the outside chance that its not, if you do

(setq t nil)

then the system catches it with a modern-day version of Maclisp's old
"veritas aeternae" message.  However, if you do

(set 't nil)

which should amount to the same thing, then it somehow slips by, and 
t evaluates to nil.  I tried to undo the damage with 

(set 't t)

and this did not work, so I guess you do have to reboot the system (I
will do this after sending this message).  However, at least simple
predicates and conditional actions based upon them continue to work
normally.

I'd be interested to know exactly what this *does* break.
