Yes. I understand from the family Java expert that (surface syntax 
issues aside) the second is similar to the way Java does this, in fact, 
so there's some precedent. That would mean that your first would 
actually mean each variadic arg has to be an array of ints, which we 
might well want to provide for.

So with that modification I'll be lots happier with the feature.
