Subject: Last iteration condition

Hi,

   How could I know that current iteration is the last in the series?
   For example:

[1, 2, 3, 4, 5, 3, 4].each do |element|
   print element.to_s
   print ',' if !LAST
end

P.S. This is just an example. I don't want to use "join". My program
logic is much complicated than this example.

Thank you.
