Impl Error for Infallible

[a1phyr]

Is there a reason why std::convert::Infallible does not implement std::error::Error ? I could not find anything about this, apart from the planned replacement by ! type.

If not, could this be implemented ? It would be very useful for generic code, and would not be complex as Infallible already implements Debug and Display.

Actually Error is implemented for std::string::ParseError, which is an alias to Infallible. It seems a bit weird for it to be done this way, shouldn't we move the impl to Infallible ?
