Subject: case question

I'm using case to do stuff based on some options that get passed on the
command line.  I've got the following bit of code that is doing this for me:

require 'getoptlong'

opts = GetoptLong.new(
    ['-t', GetoptLong::REQUIRED_ARGUMENT ],
    ['-n', GetoptLong::REQUIRED_ARGUMENT ],
    ['-s', GetoptLong::REQUIRED_ARGUMENT ]
)

opts.each do |opt, arg|
#   puts "Option: #{opt}, arg #{arg.inspect}"
    case opt
        when "-t" then title     = #{arg.inspect}
        when "-n" then nation    = #{arg.inspect}
        when "-s" then submitter = #{arg.inspect}
        else puts "You shouldn't be here with #{opt} and #{arg.inspect}
    end
end


This is taken with very little alteration from TPP (page 83: Case
Expressions).  But when I run this code, I get the following error:

eris> ./new-deck.rb -t foo -n bar -s baz
./new-deck.rb:27: parse error
                when "-n" then nation    = #{arg.inspect}
                    ^
./new-deck.rb:33: unterminated string meets end of file
./new-deck.rb:33: parse error


Can someone tell me where I've lost my way here?
