Sure, they always have (think map). The trick is, what happens when
you embed them in code, as the above does, or some macros would like
to do. In the early work towards AOT I wasn't able to serialize fns,
such serialization being necessary for putting constants in to
bytecode. I've relaxed that restriction for fns that are not closures
- they are now print-dup'able.
