Can you help me think of situations in which replacing (lambda ()

Ikarus already rewrites
  (lambda () (null? '()))
as
  (lambda () #t)
by default.  It must be something else in your program that's
causing the different behavior.  If you really think there's a
bug, try to reduce it to the smallest example that exhibits
the issue.
