Comments on the Issue (you are @copilot in this section)

@youknowone This is mostly rust proc-macro work. It will be a sort of easy issue for people who used to write proc-macro code. Otherwise it might be quite confusing because proc-macro has its own ecosystem a little bit different from common rust code. I will recommend this issue for someone who want to have experience to edit proc-macro code.

Adding exclude to rustpython_derive::py_freeze! will be a good starting point.</comment_new>
