seq test case 03 fail

[apodemakeles]

Hi, my code failed when executing seq test case 03, the output is:

ACTUAL OUTPUT:

I even tried to print the result TokenStream before returning and it looks totally correct (begin with "compile_error" as ident). Download someone else's code from github and test, same output...

rust version: 1.75.0

dependencies:

proc-macro2 = "1.0.81" syn = { version = "2.0.59", features = ["full", "extra-traits"] } quote = "1.0.36" prettyplease = "0.2.1"

This passes in the reference implementation, so it is definitely possible to implement as shown.

If you take this question to any of the resources shown in https://www.rust-lang.org/community, plenty of people have experience writing macros and should be able to help you sort it out.
