… r=chenyukang Mark `Tuple` and `FnPtr` traits `#[fundamental]` This makes it possible to write certain blanket implementations over these traits that would be impossible otherwise, at the cost of making it a breaking change to add new implementations of these traits for existing types. I doubt we plan to convert existing types into function pointers or tuples, so this seems fine. @rustbot label F-fundamental

This makes it possible to write certain blanket implementations over these traits that would be impossible otherwise, at the cost of making it a breaking change to add new implementations of these traits for existing types. I doubt we plan to convert existing types into function pointers or tuples, so this seems fine.
