Subject: Re: if statements and case statements questions

Ruby switches expand to the === operator, for example:

case string
when "" then puts "Empty"
when /^a/ then puts "Starts with a"
end

is equivalent to:

if string === ""
  puts "Empty"
elsif string === /^a/
  puts "Contains a"
end

Your first way of doing things, with the three if statements, you should 
change the last two to elsifs.
