问题
In Clojure, what is the difference between fn and fn*? I see fn* when I syntax quote a function created with the # macro. For example, in the REPL:
user=> `#(inc %)
(fn* [p1__342__343__auto__] (clojure.core/inc p1__342__343__auto__))
Is this simply used for debugging purposes to identify that the function was created by # rather than fn directly?

According to this post on google groups fn* is a primitive form to create functions and fn is a macro built on top of it to implement higher-level features like destructuring.
