好像比較有趣，程序比較小，還沒有時間看。據作者說性能不錯：

"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，比較有趣的是Exception的處理，下面是它給出的例子：

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      /*  就是這里，呵呵，還可以redo，有趣。 */
????finally
????????assert (head is true, "eh?")
????????/*
????????????Lets do this right
????????*/
????????println (' World!')
????;;
