Suggested policies:

• Forbid nil. This is the current policy. A nil as a value or key in any collection will trigger a NullPointerException.
• Elide nil. Nil elements in sets and lists will be omitted. Map entires with nil key or value will be omitted.
• Always use optional: all elements of all collections will each be wrapped in an Optional.

Bonus points for:

• Use optional when required: values or keys of any given collection may or may not each be wrapped in an Optional, depending on wether this particular collection contains at least one nil or not.

Currently "(1 2)" and "[1 2]" will both print as "[1 2]". Both are parsed as ImmutableList, which implements RandomAccess. Everything that implements RandomAccess is currently printed as a vector by edn-java.
