  Core and builtins
  
+ - File objects are now their own iterators.  For a file f, iter(f) now
+   returns f (unless f is closed), and f.next() is similar to
+   f.readline() when EOF is not reached; however, f.next() uses a
+   readahead buffer that messes up the file position, so mixing
+   f.next() and f.readline() (or other methods) doesn't work right.
+   Calling f.seek() drops the readahead buffer, but other operations
+   don't.  It so happens that this gives a nice additional speed boost
+   to "for line in file:"; the xreadlines method and corresponding
+   module are now obsolete.
+ 
  - Encoding declarations (PEP 263, phase 1) have been implemented.  A
