Subject: Re: Why `10` not returned without the `return` from the block ?

But why mean to say when the below code works:

class Simple
def foo
2 + 2
end
end
#=> nil
simple = Simple.new
#=> #<Simple:0x11eb390>
simple.foo
#=> 4


Why not the below:

class Fixnum
def to_s
self + 5
end
end
#=> nil
puts 10
#<Fixnum:0x000015>
#=> nil

Hope my confusion is clear.
