Description
Currently rust has both the traits std::str::FromStr and std::convert::From<T>, the latter of which is often implemented for T: String even when std::str::FromStr is not.
Can implementing std::str::From<String>/std::str::From<&str> provide a free implementation of std::convert::FromStr so that this problem is avoided? From<&str> (being exception-free) can be used to implement FromStr, even if the converse isn't true.

Research direction
Start with the issue discussion and the linked PathBuf documentation, then review Rust's From and FromStr trait rules. Determine whether the proposed relationship is compatible with trait implementation constraints and the RFC process; done means a reviewed design decision or RFC specification, not just a localized code change.
