Hi All
Now another hitch:

1  class Person
2  attr_reader  :genre, :style
3  protected  :genre
4  private :to_s
5  def psedonym
6    @name
7  end
8
9  def to_s
10    "just another person"
11  end
12  #private :to_s
13 end
14
15 p= Person.new
16 puts p
17 puts "********"
18 puts p.to_s

+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
CASE I
With the above class the output comes out to be:

>ruby yet.rb
just another person
********
just another person

CASE II
Now when I comment Line 4 and Uncomment Line 12, the output comes to be:

>ruby yet.rb
just another person
********
yet.rb:18: private method `to_s' called for just another person:Person
(NoMethodError)
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

THE HITCH

In first case it appears that that private declaration had no effect,
thus the textual position matters here; If this is really so, can anyone
explain why??

AND

In second case why the private declaration had no effect on
 puts p
when in fact (this is what i infer) it uses the same method which
 puts p.to_s
uses.

Can anyone Explain this bias???

Thanks
Raja
