    ContextEntry::Variable(Value::Number(24.into())),
);
// Map a function
context.insert(
    "mul".to_string(),
    ContextEntry::Function(Box::new(|args| {
        let a = args[0].as_f64().unwrap();
        Value::Number(Number::from_f64(a * 10.0).unwrap())
    })),
);
let evaluator = Evaluator::new(context);
