can't easily make a generic tuple

[timsgardner]

Would be nice if this worked:

(m/faster
  (System.Tuple/Create :a :b))

Instead, throws:

clojure.lang.ExceptionInfo: Could not find static method Create with args [clojure.lang.Keyword clojure.lang.Keyword] for type System.Tuple while analyzing form (System.Tuple/Create :a :b)

Without Magic, the following works:

(System.Tuple/Create (type-args clojure.lang.Keyword, clojure.lang.Keyword) :a :b)

but the type-args defeat the purpose, you might as well construct the Tuple directly. In Magic, this doesn't work:

(m/faster
  (System.Tuple/Create (type-args clojure.lang.Keyword, clojure.lang.Keyword) :a :b))

throws:
