I am aware that there are functions for seeing history count, min count etc. Why is the actual history hidden? For example, if there is a ref: (def a (ref 1)) (dosync (alter a 2)) (dosync (alter a 3)) (ref-history-ocunt a) =>2 a =>3
Why this is not allowed?: (ref-history a) => (2 1) If I am right, Ref implementation stores that information in tvals field which is package protected, and no methods are provided for accessing it. Of course, I could implement a subclass of Ref or access it reflectively in java and then write history function, but why it is not in the clojure core? Is this on purpose (and what is the reason), or it's just that nobody thought that would be useful? Of course, I am talking about the read-only access to the history.
