Subject: array.each restart when array is changed

Hi!


How to restart a "each" iteration when the iterated array is changed? I do
it like this

changed=false
while (changed)
changed=false
array.each {|e|
  if (today_is_christmas)
    array=array+=["Hello santa claus"]
    changed=true
  end
}

Is there a more elegant way to do this?


Second question:
why is this not allowed

#show me the first n letters of the alphabet
('a'...'a'+gets.to_i).each{|e| puts e }

How to do it the right way?

Thanks in advance,
 Kevin
