Subject: Block variables

Dear all,

I'm new comer in Ruby Forum and Ruby.

When I read a page about the *block variables* [followed link]

http://rubylearning.com/satishtalim/ruby_blocks.html

With the snipet

   x = 10
   5.times do |x|
     puts "x inside the block: #{x}"
   end

   puts "x outside the block: #{x}"

and the output is:

# x inside the block: 0
# x inside the block: 1
# x inside the block: 2
# x inside the block: 3
# x inside the block: 4
# x outside the block: 10

And they say "You will observe that after the block has executed, x
outside the block is the original x. Hence the block parameter x was
local to the block."

I tested with my Ruby 1.8.7
and the output must be:

# x inside the block: 0
# x inside the block: 1
# x inside the block: 2
# x inside the block: 3
# x inside the block: 4
# x outside the block: 4

So the question is here: Why are they different here ? Problem is from
version or this page has mistake ?
