Subject: How to get the value of a singleton class?

Here is a sample code:

str = "ABC"
class << str
  p self
end

What I get is somthing like "#<Class:#<String:0x15d4bb0>>".

If "p str", there's an error message:

x.rb:3:in `singletonclass': undefined local variable or method `str' for
#<Class:#<String:0x1625bf8>> (NameError)

How can I get the value of str("ABC") within the class << str;...;end
block?

Thank you.

Joey
