That can be shortened to:
puts line if line == line.reverse?
Note the chomp!

I've been working on this piece of code and it's starting to
drive me crazy. I think it's a problem with reference vs
value type, but I'm not sure. I'm just writing a simple
program to process a list of words and print out all the
palindromes (words that read the same forward and backward)
Here is my code:
file = File.open("testdict.txt", "r" ) do |file|
file.each_line("\n") do |line|
#filelist.push( line )
if (line == line.reverse)
I've made sure each line is being read properly, and it is.
The if statement never returns true, however. I'm new to
ruby, so I'm probably just doing something really stupid, but
I can't figure it out yet.
