New # macro character?

	Would anyone object to a new # macro character "N"? #N would do the
analogous thing for NIL (the language) that #M does for MacLisp and #Q does
for the LispMachine. Thus #N FOOBAR would cause FOOBAR to be read in only
for NIL and be ignored in MacLisp and on the LispMachine.
