The primary use of "..." is to get an object which prints a certain way.
Things like EQ are something you shouldn't depend on any more than EQ-ness
of lists. "..." is defined on non-Multics Maclisp to return an uninterned
symbol which has been SETQ'd to itself (so that it self-evaluates). You should
normally check .INFO.;LISP NEWS for descriptions like this as almost all 
recent ITS features are documented there in some form or another. -kmp
