I plan to add a Typed_racket version, which is written in typed racket, a sister language of racket with a static type-checker. The performance, though, is even worse than the Racket_compiled version. The reason appears to lie in the absence of standard libraries, with typed/racket providing all bindings I need. Could you please give it a shot?
