@foo[*-1] would return 'c'. @foo[*-1]:k would return 2. So the question is whether @foo.end returns @foo[*-1] or @foo[*-1]:k. You might also allow 'end' to take an adverb the way that 'postfix:[]' does, allowing you to explicitly choose what you want returned; but that still doesn't answer the question of what to return by default. -- Jonathan "Dataweaver" Lang
