_createMacroExpression closes over code that other transforms may edit.

Take for instance the following

```ts
assert(`my assertion`, SOME_VAR);
```

This library will close over `SOME_VAR` when building out the transformation ` _createMacroExpression`. Since the built transformations are not flushed until program exit, other transforms that edit or replace `SOME_VAR` will have no affect.

从 _createMacroExpression 转换开始，追踪已构建的转换相对于后续转换何时被刷新。重现 assert("my assertion", SOME_VAR) 的情况，然后验证其他转换对 SOME_VAR 所做的编辑或替换是否反映在最终输出中。
