<one two three>.map({$_}) ~~ set(<two three one>) This Seq has already been iterated, and its values consumed (you might solve this by addding .cache on usages of the Seq, or by assigning the Seq into an array) Although this might not be a bug per-se I don't think this is a nice thing to do to users so this ticket is to suggest that Setty.ACCEPTS can be implemented to stop this happening.
