我曾经写过一种编程语言，它有一个“strfry”操作符:

"hello world"?
# => "wdo rlholle"

有用的,是吗?

通知7。一个有效程序的例子:

    Chomsky is a room. 
    A thought is a kind of thing. 
    Color is a kind of value. 
    The colors are red, green and blue. 
    A thought has a color. It is usually Green. 
    A thought can be colorful or colorless. It is usually colorless. 
    An idea is a thought in Chomsky with description "Colorless green ideas sleep furiously." 
    A manner is a kind of thing. 
    Furiously is a manner. 
    Sleeping relates one thought to one manner. 
    The verb to sleep (he sleeps, they sleep, he slept, it is slept, he is sleeping) implies the sleeping relation. 
    Colorless green ideas sleep furiously. 

像图灵机模拟器这样的其他愚蠢的东西可以找到。

Delphi不关心像“word”这样的类型转换，将读取数组arr[0..65535] where pos = 65535: Arr[单词(pos + 10)]

这是我最喜欢的一个，你可以在Java中不使用main()来执行println。

这将编译和运行，给出println，但也有一个异常(java.lang。NoSuchMethodError:主要)

class Test {
    static {
        System.out.println("I'm printing in Java without main()");
    }
}

Ruby

时间。Parse经常假装解析没有失败，而是返回现在

require 'time'

Time.parse '2000-01-01 12:00:00'
# -> 2000-01-01 12:00:00 +0100

Time.parse '2000-99-01 00:00:00'
# -> ArgumentError: argument out of range ...

Time.parse 'now'
# -> 2010-08-13 21:26:13 +0200

Time.parse 'yesterday'
# -> 2010-08-13 21:26:18 +0200

Time.parse 'billion years ago'
# -> 2010-08-13 21:26:37 +0200

在PowerShell中，你可以重命名变量:

> $a = "some value"
> $b = "a"
> $c = "d"
> Rename-Item variable:$b $c
> $d
some value

间接间接!PHP!

字面也有用:

> Rename-Item variable:d e
> $e
some value
