glob, unlike readdir, does not look for "hidden" files unless you explicitly include them in the pattern. And if you do so, you'll find also the standard directory entries . and ..:

/home>cd /tmp/
/tmp>mkdir foo
/tmp>cd foo
/tmp/foo>touch .hidden
/tmp/foo>perl -E 'die "oops" unless !!<*>'
oops at -e line 1.
/tmp/foo>perl -E 'say for <*>'
/tmp/foo>
/tmp/foo>perl -E 'say for <.*>'
.
..
.hidden
/tmp/foo>
