 This effects the other functions that act on the list.

-Writes the list to the file. Either the current working file or something
+Either writes the current working file or the passed in argument
 that can be recognized by file(). 
 
 If you specify a filename it will save to that file and update the paths.  
 Additional changes to the object work on that file.

+In list context returns a list, it scalar context returns an array reference to the list.
