No.  It won't help functions with two or more parameters.  I like the
idea that enables sin(numarray) etc.  Perhaps something like the
following will do.


  module Math
    def sin(obj)
      if obj is known object
        ... calculate sine ...
      else
        obj.type.sin(obj)
      end
    end
  end


|By the way, I think Math function should be also defined in Math::Libm. 

I don't get the point.  Math is too broad word for the libm functions?
