Using the same file as stdin and stdout

The following, of course, doesn't work:

sed -e s/foo/bar/g < x > x

But is there any way to have the same file as input and output using
any form of shell redirection, but WITHOUT using a temporary file?

That is just with shell constructs without using, e.g.  the inplace
option to 'perl'.
