haxe中的代码替换宏？
Code replacement macro in haxe?
如何将所有出现的 fun 替换为 function，而不明显地将 function 之类的东西变成 functionction。
在使用 fun 时，我将如何消除对 return 的需求？
我不认为你可以用宏引入新的关键字，你必须使用某种有效的语法，你可以将其转换为其他有效的语法。
A basic macro is a syntax-transformation. It receives zero or more expressions and also returns an expression. If a macro is called, it effectively inserts code at the place it was called from. In that respect, it could be compared to a preprocessor like #define in C++, but a Haxe macro is not a textual replacement tool.
