Enum ExprData 

pub enum ExprData {
    Symbol(SymbolId),
    Integer(Box<BigInt>),
    Rational(Box<BigRational>),
    Real(Real),
    Add(Box<[ExprId]>),
    Mul(Box<[ExprId]>),
    Pow {
        base: ExprId,
        exp: ExprId,
    },
    Apply {
        f: ExprId,
        args: Box<[ExprId]>,
    },
    Indeterminate(IndeterminateForm),
}

Node in the symbolic world (spec §8.1). Add/Mul are stored as canonically ordered n-ary lists (spec §8.4), so equality is ExprId equality (O(1)).
