I guess that is another case. But then the OS doesn't even necessarily
think they are the same file.

Well, the lexically earlier error was a elaboration error, while the later
(reported) error was a syntax error.

Not sure what you are asking for here?

Arguably, MLton goes one step further. We don't even attempt to ascribe
meaning to a program that has any lexical or syntax errors.
