Something like
def option[T](v: T): Option[T] = if (v == null) None else Some(v)
I'm perfectly happy defining this utility method myself, but just wondered if it already exists somewhere.

Not that `Option#apply` is new in Scala 2.8. Also new is the inverse operation, `Option#orNull`.

I would also absolutely love this in 2.7.7. You can roll your own quite easily though.
