Struct ClassInfo 

pub struct ClassInfo {
    pub name: Symbol,
    pub params: Vec<Symbol>,
    pub supers: Vec<Symbol>,
    pub methods: BTreeMap<Symbol, Scheme>,
}

Semantic information about a type class declaration, derived from Rex source.

Design notes (WARM):

• We keep this explicit and data-oriented: it makes review easy and keeps costs visible.
• Rex represents multi-parameter classes by encoding the parameters as a tuple in the single Predicate.typ slot. For a unary class C a the predicate is C a. For a binary class C t a the predicate is C (t, a), etc.
• This keeps the runtime/type-inference machinery simple: instance matching is still “unify the predicate types”, and no separate arity tracking is needed.
