Subject: How do I unsplat something?

Hi,
Is there any easy to unsplat an item?
ie. 1 becomes [1]
    [2,3] remains [2,3] ?

so far i found:
a = *[1]
*b = *a   #=> [1]
a = *[1,2]
*b = *a   #=> [1,2]

but this doesn't work if a is a hash, because hash overrides the to_a
method
a = *[{"a"=>1}]
*b = *a    #=>  [["a",1]]  when i actually want: [{"a"=>1}]

Thanks for helping
  -Patrick
