这个情况下，规范是如何定义该如何处理的？

: firefox在做语法分析之后就改变了js函数的内容，比如某些无论如何都执行不到的block就被删除掉了
: 但我记得好像之前还有谁研究过在function里头写特定的注释来完成某些逻辑的，那这些逻辑可能就会被firefox的优化破坏掉。。

...发现我猜不出会执行成什么样子
因为从来都是匿名函数用到死……

没错

... Also, an ExpressionStatement cannot start with the function keyword because that might make it ambiguous with a FunctionDeclaration.

其他的xxx Statement就更别说了。

新版本也是这样，而且特别说：

NOTE Several widely used implementations of ECMAScript are known to support the use of FunctionDeclaration as a Statement. However there are significant and irreconcilable variations among the implementations in the semantics applied to such FunctionDeclarations. Because of these irreconcilable difference, the use of a FunctionDeclaration as a Statement results in code that is not reliably portable among implementations. It is recommended that ECMAScript implementations either disallow this usage of FunctionDeclaration or issue a warning when such a usage is encountered. Future editions of ECMAScript may define alternative portable means for declaring functions in a Statement context.

: lexical structure规范里规定好了的.
: FunctionDefinition不会出现在if else这类东西内部.如果出现了,各家怎么处理只能算附赠了.
: FunctionExpression就可以.
: 以前的js是这样,新版本的没看过,不知道...
