CoffeeScript 1.11.0 发布，脚本语言

CoffeeScript 1.11.0 发布了。

offeeScript这一门编程语言构建在JavaScript之上，其被编译成高效的JavaScript，这样你就可以在web浏览器上运行它，或是通过诸如用于服务器端应用的Node.js一类的技术来使用它。编译过程通常都很简单，产生出来的JavaScript与许多的最佳做法都保持了一致。

此次更新内容：

CoffeeScript now supports ES2015 import and export syntax.
Added the -M, --inline-map flag to the compiler, allowing you embed the source map directly into the output JavaScript, rather than as a separate file.
A bunch of fixes for yield:

yield return can no longer mistakenly be used as an expression.
yield now mirrors return in that it can be used stand-alone as well as with expressions. Where you previously wrote yield undefined, you may now write simply yield. However, this means also inheriting the same syntax limitations that return has, so these examples no longer compile:
```
doubles = ->
  yield for i in [1..3]
    i * 2

six = ->
  yield
    2 * 3
```
The JavaScript output is a bit nicer, with unnecessary parentheses and spaces, double indentation and double semicolons around yield no longer present.

Improved several error messages.
Just like undefined compiles to void 0, NaN now compiles into 0/0 and Infinity into 2e308.
Bugfix for renamed destrucured parameters with defaults. ({a: b = 1}) -> no longer crashes the compiler.
Improved the internal representation of a CoffeeScript program. This is only noticeable to tools that use CoffeeScript.tokens or CoffeeScript.nodes. Such tools need to update to take account for changed or added tokens and nodes.
Several minor bug fixes.
