Hi David, any? would be redundant and less general than some, if I am not mistaken. Compare the docstrings for the hypothetical "any?".
(some p coll) Returns the *first logical true value* of (pred x) for any x in coll, else *nil*. (any? p coll) Returns *true* if (pred x) is logical true for any x in coll, else *false*. Since *nil* and *false* are both falsy, "some" can be used as a predicate that is truthy when it finds truthy result, otherwise falsy. This is exactly the behavior expected from an any? function. "some" is a poster boy for Clojure's well thought out truthyness system, this is a great example of the types of general functions it allows. Perhaps a pointer to "some" should be added in the docstring of "not-any?". Although a quick look at the source makes it crystal clear. I wasn't aware of "not-any?"s existence, maybe noting it in "some"s docstring could be beneficial also.
