Very interesting and radical indeed! ^_^

This is reminiscent of a comment at the bottom of arc.arc:

  ; solution to the "problem" of improper lists: allow any atom as a list
  ;  terminator, not just nil.  means list recursion should terminate on 
  ;  atom rather than nil, (def empty (x) (or (atom x) (is x "")))
It also reminds me of a feature in PicoLisp: symbols evaluate to nil by default instead of raising an undefined variable error.
