How can I use Array#delete while iterating over the array?

Question

I have an array that I want to iterate over and delete some of the elements. This doesn\'t work:

a = [1, 2, 3, 4, 5]
a.each do |x|
  next if x < 3
  a.del

You don't have to delete from the array, you can filter it so:

a = [1, 2, 3, 4, 5]

b = a.select {|x| x < 3}

puts b.inspect # => [1,2]

b.each {|i| puts i} # do something to each here
