Same with me, but the expected ugliness will be low:


        E{ugliness} = Sum[ugliness(case) * Prob{case} : case].

And if you really need the rest-list thing (the day will come),
the meaning will at least be obvious.

At the point I decide to drop rest-list values the SRFI will be withdrawn, I promise.
The whole point of this SRFI is to integrate multiple values in all their beauty
smoothly into the Scheme language.
