It's very interesting the use of `(fl+ sum)` to make the code faster. I think the compiler could be improved to make it unnecessary but I don't know how to do that and how hard is it. So I made a feature request in [[Feature Request] Sometimes code with unboxed flonum get faster wrapped with fl+ · Issue #4774 · racket/racket · GitHub](https://github.com/racket/racket/issues/4774)
