No. The summary is: from Java's point of view every function is "willing" to accept any number of args, but many of the implementations throw an exception. Vars have an :arglists metadata key, but that is not generally present on functions. I agree it would be nice if function objects carried a set of "acceptable arities" with them, but I haven't thought very hard about it - perhaps the performance implication this imposes on every function isn't worth it for the small minority of times when you need to ask the question.
