In the "clean" API yes.
But it would be nice to also have an easy API for small scripts, hence
my "autotextfile" proposal.
(and, it would also avoid making life too hard for beginners trying to
learn the language)

> f = open(fname, 'r', string.guessencoding(fname))

This one is inefficient because it results in opening the file twice:
once in string.guessencoding(), and once in open().
This does not happen if there is a special argument instead, like
"by_content=True" in my proposal.

Cheers
