The Qu Programming Language 1.06 (Default)

好像比较有趣，程序比较小，还没有时间看。据作者说性能不错：

"All I can tell you is that on my Pentium(R) 4 CPU 1.70GHz 
with 256 KB Cache and 256 MB RAM running Linux 2.4 and KDE-2, 
Qu is generally faster than Perl-5.6, Python-2.3 and Ruby-1.8. 
It is significantly slower than C, of course."

支持Exception和OO，比较有趣的是Exception的处理，下面是它给出的例子：

hello

sub hello (msg = nil)
    ```
    Prints a message for the world.
    ```
    local head = false
    do try
        msg is Str or throw EArgType, "me want string"
        msg.('len') or throw EArgValue
        print (msg.ufirst)
        head = true
    catch EArg
        msg = `hello`
        redo      /*  就是这里，呵呵，还可以redo，有趣。 */
    finally
        assert (head is true, "eh?")
        /*
            Lets do this right
        */
        println (' World!')
    ;;
;;
