If you're talking about treating 0 as falsy, then why not redesign 'pos in the process? I would happily use a 'pos that worked like this:

  > (pos 1 '(1 2 3))
  (0)

Oh, there's also the issue with 'find. It's already cumbersome to search a list of booleans for false and a list of lists for an empty list, and now it would be difficult to search a list of numbers for zero.

Of course, we could just do the same thing as 'pos:

  > (find 0 '(1 2 0 3))
  (0)
