tag trace easy
done
I can come up with a use-case: what about using trace to view the state
of a hashtable before and after a function call: something like
(trace foo :print-all (gethash 'key *table*))
It would be quite annoying for NIL to be printed, and then having to
worry about whether that actually means "key not present" or "key has
associated value NIL in *table*".
