I had a similar problem recently and Rich proposed the following
solution, which works fine for me:
Since Clojure already does this, you can borrow its implementation,
found in clojure.lang.Reflector. In this case, see invokeConstructor.
(clojure.lang.Reflector/invokeConstructor (class (ref "foo")) (to-
array [42]))
=> #<r...@6ad3c65d: 42>
