Ceylon 的第 6 个里程碑进度报告，JVM上的新语言

Ceylon是一个针对在团队环境中写大型程序的编程语言，该语言意图消除目前Java存在的问题。Gavin描述了他对Ceylon的目标：运行在JVM之上，静态类型，自动内存管理，内置模块化。

Ceylon语言支持功能强大的类型系统，在设计时它考虑到了以下限制：所有类型在类型系统内部都必须是可表达的（没有特殊的 primitive类型或者复合类型）；Ceylon的t通用类型系统要比Java的更简单，而且相比于其他类Java语言，它的安全性更高；甚至元编程（reflection）也必须是类型安全的；另外，Ceylon必须是在JVM上执行，而且可以和Java交互操作。

So it looks like it's time again for me to offer my usual lame excuses for another late milestone release of Ceylon. Well, I suppose all that really matters is: it's coming soon!

Ceylon M6 will be the first feature-complete implementation of the language specification, incorporating the following headline changes:

• new syntax for invoking super-interface members,
• nonempty variadic parameters
• try with resources,
• the ** scaling multiplication operator,
• "static" member references,
• metamodel and metamodel expressions, and
• annotations.

We have not yet decided if support for serialization will make it into M6.
