Crumb：无关键字、一切皆函数的编程语言

Crumb 是一门函数式编程语言，没有 “关键字”，一切皆函数 (0 keywords, everything is a function)。

其他特性包括提供垃圾回收 (GC)、动态类型、具有简洁的语法和详细的标准库。

示例代码

 table = (map (range 10) {_ y -> <- (map (range 10) {item x -> <- (multiply (add x 1) (add y 1)) }) })

 (loop 100 {i -> i = (add i 1) (if (is (remainder i 15) 0) { (print "fizzbuzz\n") } { (if (is (remainder i 3) 0) { (print "fizz\n") } { (if (is (remainder i 5) 0) { (print "buzz\n") } { (print i "\n") }) }) }) })

• 实现斐波那契数列

 // use a simple recursive function to calculate the nth fibonacci number fibonacci = {n -> <- (if (is n 0) {<- 0} { <- (if (is n 1) {<- 1} { <- (add (fibonacci (subtract n 1)) (fibonacci (subtract n 2)) ) }) }) } (until "stop" {state n -> (print (add n 1) "-" (fibonacci (add n 1)) "\n") })

标准库包括：IO、Comparisons、Logical Operators、Arithmetic 等。
