Sorry to inject in the thread, but here's more material that uses #t
and #f:

  $ guile

  scheme@(guile-user)> (= 1 1)
  $1 = #t
  scheme@(guile-user)> (= 1 2)
  $2 = #f

I don't remember ever being confused about #t and #f, so perhaps my
opinion doesn't matter much in this, but I'd prefer #t and #f because
it's already widespread use in Scheme.  (And with widespread I mean:
Pretty much all Scheme code I read).

I do remember being confused about the double parenthesis on "let" ;).

Kind regards,
Roel Janssen
