This doesn't work if you assign the strings to variables though: 'hi ' 'there' =>"hi there" hi = 'hi ' there = 'there' hi there NoMethodError: undefined method `hi' for main:Object from (irb):9 from /opt/local/bin/irb:12:in `<main>' Which is a little counter intuitive. -- Posted via http://www.ruby-forum.com/.
