还有一个特点,那就是代码块(CodeBlock)、表达式(Expression)与语句(Statement)都直接继承DLR tree类层次中的根类型Node,也就是说它们之间是相互独立的。这与IronPython AST以及其它许多严格区分表达式和语句的语言的做法一样;IronPython比较特别的地方是把类定义与方法定义也看作语句来处理。
代码语言:javascript 代码运行次数:0 运行 AI代码解释 Variable used in lambda expression should be final or effectively final 翻译过来就是说在lambda表达式中只能引用标记了 final 的外层局部变量或者虽然没有显式定义为final,但实际上就是一个final变量,否则会编译错误。 那么显然在上面的代码中的otherMap变量,在...
