use evalexpr::*;

let mut context = HashMapContext::new();
context.set_value("one".into(), 1.into()).unwrap(); // Do proper error handling here
context.set_value("two".into(), 2.into()).unwrap(); // Do proper error handling here
context.set_value("three".into(), 3.into()).unwrap(); // Do proper error handling here
assert_eq!(eval_with_context_mut("one + two + three", &mut context), Ok(Value::from(6)));
