If you don't use groups within your regexp, scan will just return an array 
with the matched strings. If you do however, it will return an array of 
arrays, each array containing one string per matched group.
Example:
>> "la=lu,lipp=lapp,slipp=slapp".scan(/\w+=\w+/)
=> ["la=lu", "lipp=lapp", "slipp=slapp"]
>> "la=lu,lipp=lapp,slipp=slapp".scan(/(\w+)=(\w+)/)
=> [["la", "lu"], ["lipp", "lapp"], ["slipp", "slapp"]]
