The "method" above is not meant to mean whatever method you
feel like.  I'm talking about Object#method that returns a
Method object for the method name/symbol given as an argument.

I'm talking about being able to do something like this:

class C
  obj = "hello world!"
  define_method(:foo,obj.method(:[]))
end

C.new.foo(0,5) # => "hello"

Instead you get an error like this because define_method tries
to redefine self for obj.method(:[]).

TypeError: bind argument must be a subclass of String
        from (irb):3:in `define_method'
        from (irb):3
