This works fine: user/ (read-string "#=(java.lang.Float. \"5\")") 5.0
However, these two cases fail: user/ (read-string "#=(.toCharArray \"foo\")") java.lang.Exception: Can't resolve .toCharArray user/ (read-string "#=(java.lang.Enum/valueOf java.lang.Thread$State \"NEW\")") java.lang.ClassCastException In the first case, it looks like the dotted method invocation isn't being expanded into the (. obj (methodname)) form, so a var named '.toCharArray' is being searched for. In the second case, I'm guessing that the classname provided as the first argument is being interpreted as a symbol and not a Class. Just for comparison's sake: user/ (eval '(java.lang.Enum/valueOf java.lang.Thread$State "NEW")) #<State NEW> (Also puzzling to me is the fact that the ClassCastException is being emitted by clojure's reflection apparatus; this is confusing to me, as Enum/valueOf has no overloads, and in any case, the types of the arguments is known -- Class and String, or in the case where the reader isn't swapping out the symbol for the Thread$State class, a Symbol and String. That's for another day, though.) I'm not entirely clear on all of the implications of #=, but it seems like a good deal of the reader functionality isn't available within #= forms. Is this known and/or expected behaviour?
