That's easy for simple types like java.util.Date, but how could it work f

A more interesting question is "why does this error exist in the first
place"? Why
`eval` invokes the Clojure compiler, which transforms data structures into
Java bytecode. The Clojure compiler understands Clojure data structures
like lists, vectors, and symbols, plus a few Java types like String and
numbers. It doesn't know what to do with a java.util.Date. "Can't embed

What does eval'ing a form containing an object reference cause an
exception? What am I doing wrong?

This is the simplest exam
You need to quote the vector so the date will be created inside eval,
instead of having the date go into eval as an element of the
(evaluated) vector.
