Subject: Re: What is Ruby's default constructor?

Now I typed directly into the IRB and it produced the same error, whose 
explanation has been provided already. But trying to understand who 
called that below version inside from the class without having any 
object creation?


@ubuntu:~$ irb --simple-prompt
>>   def Object.new initialize
>>   p "hi"
>>   end
=> nil
>> nn
