Yeah, I want to see how you do it this time ;-) So if you do a `.to_string()` on a `TokenStream`, you lose all the span [1] information ("span information" is a term invited by me, hope I get it right ;-))

Not important: I meant I am not a procdure macro expert, hope "span information" is what is used when discussing span preservation ;-)

e.g. if there is a compile error in the test code, the compiler cannot report the exact line of the error, it can only report there is an error.
