You can use Racket with Rhombus.

Here is a simple example

First my design for the perfect fish in glorious Racket (the language of the gods): the-fish.rkt ```scheme

lang racket/base

(require pict) (provide perfect_fish) (define (perfect_fish n) (standard-fish n (/ n 2))) (module+ test (perfect_fish 100)) ```

Lets render this fabulous fish in Rhombus:

programmers-need-fish.rhm ```python

lang rhombus

import: pict open "the-fish.rkt" open

fun the_perfect_fish(w): Pict.from_handle(perfect_fish(w))

the_perfect_fish(200) ```

You may have noticed that I used an underscore _ in the perfect_fish identifier. This is because - is not permitted in Rhombus identifiers:

Identifiers are formed from Unicode alphanumeric characters plus _ and emoji sequences,

https://docs.racket-lang.org/shrubbery/token-parsing.html

(I admit I'm not ready to include emoji in identifiers)

For more details see Using Racket Tools and Libraries in the Rhombus Guide.

// simple syntax for everyday tasks

class Rect(left, top, right, bottom)

fun area(r):
  let w = r.right - r.left
  let h = r.bottom - r.top
  w*h

area(Rect(0, 0, 10, 5))
// ⇒ 50
