Subject: puts a . which method of array is called

a = w(1 2 3)


puts a

prints
1
2
3


I implemented
class  Array
  def to_s
    'to_s is called'
   end
  def to_str
    'to_str is called'
  end
end


I am not able to find when I do 'puts a' which method of a is called. I
also tried inspect and to_ary method but doesn't seem to work.


Also I would like to know how to go about finding which method is called
without looking at the c file. Is there some kind of trace I can do to
detect which method was called?
