There must be code inside like that:
if block_given?
yield index

That wouldn't do the setting of the values in the array. Maybe:
if block_given?
size.times { |index| self yield index }
end
or, if it already
I was always under assumption that the block accepts the return value
of the iterator as the argument to the block, but look at this:
Array.new(500) do | i |
puts i
end
I expect i to be an array instance with 500 indexes all will nil
values. However, what it returns is indeed an array

thanks for response but that was just an example and not really what
my question was about.
Perhaps this is a better example:
Array.new(10) do |id|
? '#{(id + 1).to_s.rjust(2,0)}'
end
= ['01', '02', '03', '04', '05', '06', '07', '08',
