- Real named functions! Functions are no longer tokens, and can now be created in a
Computer, similar to variables.
let mut map = HashMap::<String, &'a Fn(f64) -> f64>::new();
map.insert("sqrt".to_owned(), &|n| n.sqrt());
- RSC is fully generic, now! Types that can support addition, subtraction, and a couple functions necessary in the
Num trait can be lexed, parsed, and computed with no changes to the RSC source code.
- Getting the previous answer with the new
ans variable. ans does not exist until you've run a calculation on a Computer already.
- Factorial:
5! = 120
