I would do it like this ...

  class SomeType
    def somefunction
      expression1
    end
  end

  class SomeOtherType
    def somefunction
      expression2
    end
  end

Then just call:   

  a.somefunction

If you still feel the need to pass obj as an argument to somefunction, you
can always use:

  def somefunction(a)
    a.somefunction
  end
