Subject: Arrays, symbols and association - looking for better idiom

Hi all,

I'm trying to associate non-symbol arguments with the most immediately previous 
symbol.  The solution below works, but I suspect there's an easier way:

def test(*args)
    hash = {}
    current = nil
    args.each{ |arg|
       if arg.is_a?(Symbol)
          hash[arg] = []
          current = arg
       else
          hash[current] << arg
       end
    }

    hash
end

hash = test(:foo, 1, :bar, 'a', 7, :baz, /hello/, Fixnum)

p hash # {:foo=>[1], :bar=>["a", 7], :baz=>[/hello/, Fixnum]}

Any ideas?  Some Array#assoc trick I'm missing?

Thanks,

Dan
