No, just that it doesn't work for pipes, so the data you're reading
has to be in a named file, not produced as the output of another
program.  But even in that case, you could do it like this:

while read line; do ...; done <<EOT
$(data-producer-command)
EOT

That will also ensure that the last line ends with a newline, but the
$() command substitution will also remove any trailing empty lines,
which might be a problem, depending on what you're doing.
