I like the fact that currently unicode(x) is guarateed to return a
unicode instance, or raises a UnicodeDecodeError.  Same for str(x),
which is guaranteed to return a (byte) string instance or raise an
error.

Wouldn't also a new function make the intent clearer?

So I think I'm +1 on the text() built-in, and -0 on changing str.
