Actually, is the other way around. EXIT just returns and UNSET! value. In REBOL every function returns something, even if this something is an UNSET! value (which means "I didn't return anything useful"). > Again it's the distinction between UNSET & UNSET! >> first reduce [print "Hi!"] Hi! >> type? first reduce [print "Hi!"] Hi! == unset! >> datatype? first reduce [print "Hi!"] Hi! == false >> datatype? do [print "Hi!"] Hi! == false I can't see any difference here.
