I assume the problem with this is that it would be ambiguous. You can 
already use either a string or a file with ``et.parse``. A string is 
interpreted as a file name, while a file object is used directly.

How would you differentiate between a string that's supposed to be a 
file name, and a string that's supposed to be XML?
