Re: [swift-users] Range.count can abort

Is there any reason that Distance has to be a simple Int? Since it’s defined per-type, UInt64 could use a custom struct without impacting the performance of other types: struct UInt64Distance : Comparable { //I'm not sure what else it needs to conform to var distance: UInt64 var
