Subject: [RCR] Array#push(empty array expanded) => no exception

This strange behavier really surprised me.. 

irb(main):006:0> [].push(*[])
ArgumentError: wrong number arguments (at least 1)
        from (irb):6:in `push'
        from (irb):6


Why is it illigal to concatenate an empty set ?
I expected Rubys Array class to work just like a normal set.
This seems *VERY* non-intuitive to me (POLS).

Array#unshift doesn't like zero arguments neither.


An ugly hack to avoid it could be: 
   @data.unshift(*objs) unless objs.empty?



Can it be made legal to push/unshift with zero arguments ?
