如果你在开发Flex的应用，可以考虑一下这款专业级别的工具。

“Project Kotlin” is the codename for a statically-typed JVM-targeted programming language developed by JetBrains and intended for industrial use.

Why a new language?

At JetBrains, we’ve been developing for the Java platform for a long time, and we know how good it is. On the other hand, we know that the Java programming language has certain limitations and problems that are either impossible or very hard to fix due to backward-compatibility issues. We know that Java is going to stand long, but we believe that the community can benefit from a new statically typed JVM-targeted language free of the legacy trouble and having the features so desperately wanted by the developers.

JetBrains开发的IDE工具支持很多种语言，当然对语言的了解也比较深，希望这次kotlin能够给大家带来不一样的体验。

这个配置个人在用，推荐一下。
