If the or-else form is not provide and the Option is empty (aka a None object) a NoSuchElementException will be thrown. If or-else is provided, the form will be evaluated in the case of a None.

Examples:

(get (option 1)) ; => 1
(get none) ; throws NoSuchElementException
(get none :default) ; => :default
(get none (throw (ex-info "Oh no!" {}))) ; throws ExceptionInfo

Create a scala.Option. If no value is given, or the value is nil a scala.None will be returned. Otherwise the result will be a scala.Some that wraps the given value.
