You're talking about the implementation in the background, but I am talking about nice code. I'm aware that defstruct with optional keys introduce a slight overhead compared to normal hashmaps, but that is minimal and defstruct/struct-map is much cleaner and more documentary that a pure hashmap. I can not find a reason why Clojure forbids to make use of this nice feature.
