In for, in-range is faster.

http://docs.racket-lang.org/reference/sequences.html?q=in-ra...

An in-range application can provide better performance for number iteration when it appears directly in a for clause.

    -> (for ([i (in-range 1 16)])
        (match (list (modulo i 3) (modulo i 5))
          [(list 0 0) (displayln "fizzbuzz")]
          [(list 0 _) (displayln "fizz")]
          [(list _ 0) (displayln "buzz")]
          [_          (displayln i)]))

Oh, thanks for that :)

Flappy Bird in Racket | https://github.com/soegaard/flappy-bird

Man, apparently dr racket format looks like a hot mess.

A normal Racket file is a straight forward text file.

In Flappy Bird I used inline images, as in (define bird <the-bird-image-here> ) This makes it simple to distribute the source and images as a single file, but unfortunately the resulting file is not pretty.

In short: to see the source open it in DrRacket.

L++ is a programming language that transcompiles to C++. It uses Lisp-like syntax. Macros are supported via Racket's macro system define-syntax, define-syntax-rule and defmacro.
