I'd call Clojure's use of the JVM a win, not a liability.
but i agree it's not a "deep" analysis. did you miss the part where i said i had only used the language for a day? or the word "initial" in the title?
[edit:] actually, there is one more thing i want to say. one thing that has discouraged me from looking at clojure earlier is the agressiveness i've seen from the language's fanboys. fwiw.
