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). <dibblego> @check \x -> (nub . nub) x == nub x -- is nub idempotent? <lambdabot> OK, passed 500 tests. - -- Tony Morris http://tmorris.net/ -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.6 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQFIcS9LmnpgrYe6r60RAiDOAKCJlDaqNd5ssgxrUrrHee75WGzhbgCfftdn 70+4isXh4zaoYly0da2Gdk8= =ryfF -----END PGP SIGNATURE-----
