  I disagree profoundly.  I think Paul's observation is insightful and clever.

  Although a naive reader may be stumped upon seeing (or) used for `nil´,
  (and) used for `t´, (+) for 0, and (*) for 1, I imagine it would yield a very
  pleasant, mathematical realization of the trivial case for these operators.
  I certainly smiled in appreciation upon reading Paul's article.

  Once internalized, this becomes an idiom that is not at all obscure.
