I think there is no ambiguity in from_str as a method name so "choose a
less ambiguous method name" is unnecessary, and it can't be a FromStr
impl in this case because FromStr's error type cannot borrow from the
input string slice.
warning: method `from_str` can be confused for the standard trait method `std::str::FromStr::from_str`
