By the way, you didn't go into detail about my idea to remove lambda info
as a separate type. Can you explain why (if?) this needs to be a
separate type? As far as I can tell, it's just a glorified string that
lives in the procedure decoration area. I guess it's because this would
cost us at least 3 more words per closure? (but only if lambda info is
enabled, of course)
