You forgot a question mark there:

Personally, I would never write a ternary operator that was so 
confusing.  Terseness should never be favored over clarity.  And Ruby 
has four different quoting mechanisms for strings, so resorting to 
escaping quote marks inside strings isn't necessary.


last_name = "Smith"
comma = ","
quoted_last_name = %Q{"#{last_name}"}

puts last_name.empty? ? comma : quoted_last_name
