Think about removing methods from dataclasses

[hawkrives]

I've been realizing that the intent behind most "data classes" is to have no/very few methods on them, as they're intended to act like "records".

It would be interesting to experiment with making the DP classes into "records"?

Alternately, another idea might be to move from subclassing Rule > Solution > Result, to having a (say) CourseRule record, which is attached to a CourseSolution record, which is attached to a CourseResult record?

So instead of having to copy all of the properties, and subclassing as we do now, we could just essentially stick a pointer into it.

Something like

class CourseRule:
    course: str 

class CourseSolution:
    rule: CourseRule

class CourseResult:
    solution: CourseSolution
    
    def rank(self) -> Decimal:
        ... 

Hmm. Something like that.
