Oh, wow. I thought the control flow from the readme was a little annoying with the prefix -notation for bigger/smaller than;

    # Control flow
    if (> x 0) {
      (println "positive")
    } else {
      (println "negative or zero")
    }

But that's nothing compared to the scream for a case/switch-statement in the Mandelbrot example...

    # Gradient: " .:-=+*#%@"
        let gradient: string = " .:-=+*#%@"
        let gradient_len: int = 10
        let idx: int = (/ (* iter gradient_len) max_iter)
        if (>= idx gradient_len) {
            return "@"
        } else {
            if (== idx 0) {
                return " "
            } else {
                if (== idx 1) {
                    return "."
                } else {
                    if (== idx 2) {
                        return ":"
                    } else {
                        if (== idx 3) {
                            return "-"
                        } else {
                            if (== idx 4) {
                                return "="
                            } else {
                                if (== idx 5) {
                                    return "+"
                                } else {
                                    if (== idx 6) {
                                        return "*"
                                    } else {
                                        if (== idx 7) {
                                            return "#"
                                        } else {
                                            if (== idx 8) {
                                                return "%"
                                            } else {
                                                return "@"
                                            }
                                        }
