Are function types a requirement?

[Reinier Zwitserloot]

I believe I mentioned that chaining varargs into another varargs is actually
allowed (and, as the same rules apply to the chained method, does not weaken
type safety, unless you mix compilation units compiled by different versions
of java, an act which has always had ample opportunity for uncaught type
errors). If not, that's an omission in putting it down in this thread, it's
always been part of this set of rules.
