Just one more question. I know you'll be able to write

  def foo(a: 1, b: 2, c: 3)

But will you also be able to write it as

  def foo(:a => 1, :b => 2, :c => 3)

Or maybe even (as I wrote before)

  def foo(:a = 1, :b = 2, :c = 3)

I can see that the key: value thing is cool, but :key = value would also 
be nice. It is also clearer in method definitions.
