About how AST is generated

[yjhmelody]

Should the generated code use the parser to parse the new text instead of modifying the AST? Because the range field of the original code cannot locate the newly generated code, will this be unfriendly to some errors?

Yes. It will be unfriendly in some cases.

@willemneal and I are working on making it better. This takes time sometimes.
