…const, r=RalfJung Do not consider traits that have unsatisfied const conditions to be conditionally const This will improve error messages as we continue to constify traits, since we don't want to start calling things "conditionally const" if they aren't implemented with a const impl anyways. The only case that this affects today is `Deref` since that's one of the only constified traits in the standard library :) r? RalfJung
