Oops, yes.  I didn't write that, and it doesn't convey my feelings
about file() vs. open().  Here's a suggestion for better words:

"The file class is new in Python 2.2.  It represents the type (class)
of objects returned by the built-in open() function.  Its constructor
is an alias for open(), but for future and backwards compatibility,
open() remains preferred."
