re: > I believe that QUOTE has to return THE argument it is given.
[That's Aarons' comment].
I say, "Suuuuuuure, you will get THE argument". Now, the only question
is, how do you know what you were given? Use EQ, use EQL? Why?
I say, use COALESCABLEP. That's good enough for identity of constants.
The only conceivable reason why the EQ/EQL version of identity could
matter is if you allow runtime updating of "constants" -- in that case,
you need a pointer to the real place that was updated rather than a
pointer to an equivalent copy. But we are outlawing constant modification,
