OK. If this works in 1.9, then I think it's good enough.

  def foo(*args, keys)
    args  #=> [1,2,3]
    keys  #=> {:a=>1, :b=>2}
  end

  foo(1,2,3, a:=>1, :b=2}

I got this from eigenclass - Changes in Ruby 1.9:

Mandatory arguments after optional arguments allowed

(ruby-dev:29014)

   def m(a, b=nil, *c, d)
     [a,b,c,d]
   end
   m(1,2)                                         # => [1, nil, [], 2]

The problem now of course is having to do:

  def foo(*args)
    keys = (Hash===args.last ? args.pop : {})
    args  #=> [1,2,3]
    keys  #=> {:a=>1, :b=>2}
  end

So if my first example works in 1.9, then I take it back.
