partial(*args)

Convert a Proc object into new partial Proc object. 

  a = proc { |a,b,c| a+b+c }
  b = a.partial(__, 2, __)
  b[1,3] #=> 6

This method is similar to Proc#curry.

TODO: Parhaps ArgumentError would suffice, and we don‘t need MissingArgument?

  def partial(*args)
    Proc.new do |*spice|
      result = args.collect do |a|
        MissingArgument == a ? spice.pop : a
      end
      call(*result)
    end
  end
to_openobject()

Translates a Proc into an OpenObject. By droping an OpenObject into the Proc, the resulting assignments incured as the procedure is evaluated produce the OpenObject. This technique is simlar to that of MethodProbe. 

  p = lambda { |x|
    x.word = "Hello"
  }
  o = p.to_openobject
  o.word #=> "Hello"

NOTE The Proc must have an arity of one —no more and no less.
