deal in simplifying your list processing stuff) is to wrap your triples
in the
symptom list inside a functor.

Ie:
disease(1, 'Common cold', 0.02, [symptom(1, 0.9, 0.05), symptom(2, 0.8,
0.02), ...]).

Makes processing the list using simple list/set predicates much easier.

PS. Once wrote a symbolic math package for elementary group theory in
FORTRAN 77
so you've my sympathy re maths undergrads and inappropriate
implementation
language choices :-)
