Subject: Why do you think of NilClass#to_proc?

I have two minds about using a NilClass#to_proc

    class NilClass
      def to_proc
        Proc.new{ |*a| a }
      end
    end

Or

    class NilClass
      def to_proc
        Proc.new{ nil }
      end
    end

Which makes the most sense? 

I thought of the first b/c often default procedures are simply pass-thru 
procedures.

On the other hand, is neither a good idea? Is any definition of 
NilClass#to_proc simply too "dangerous"?
