Hi Michael, Sorry to distract from your issue, but I note that (nub . nub) can be replaced with just 'nub' since the function nub is idempotent (f . f == f).
Or even better, with a custom nub: in order to handle some special cases the Prelude nub is rather inefficient. -- brandon s. allbery [solaris,freebsd,perl,pugs,haskell] allbery@kf8nh.com system administrator [openafs,heimdal,too many hats] allbery@ece.cmu.edu electrical and computer engineering, carnegie mellon university KF8NH
