man perlvar explains it all , of course :-)
The two are similar, but FOO->autoflush requires IO::Handle.

The simple old way (I'm not sure if the syntax below supercedes it) is:
$|=1;
Assigning any non-false value to $| will turn off buffering.

Try the following:
perl -e 'for($i = 0; $i < 100; $i++){ print STDERR "$i"; sleep 1 ;
print STDERR "\r"}'
(I used STDERR, to avoid buffering of stdout. There is a way to
disable this, but I can't recall it off the top of my head).
iirc, you can turn off the buffering with:
STDOUT->autoflush (1);
