Depending on how you construct your predicates, you may be able to capture their composition... And then serialise that.
For example:
If you were doing some sort of range intersection predicate construction ~
R1 n R2 n R3
Could be represented as a list of those ranges [(l1,r1),(l2,r2),(l3,r3)]. Basically, instead of constructing a predicate function directly, you would assemble a data-structure representing the essence of the predicate, then convert that to both a function for evaluation, as well as a string for serialisation. This would also allow you to perform some "optimisation" before serialisation which could be fun.
Thanks, I understand I need a representation and a Set would be just one of the possiblilities.
