I kind of get the feeling that Clojure is running into the 90% milestone now (only 90% more to go!). The core the language is pretty good, but now people are starting to find the warts, and they appear largely Java related.<p>It will be interesting to see if projects like Clojure-in-Clojure will help resolve some of the niggling issues like dealing with classpaths and odd performance issues where people aren't sure if they should be passing type hints or not.
