The standard behavior for the test operators is to work strictly off of the
stat data. But, as you found out, stat is incomplete with regard to
extended permission sets.

End sum, POSIX ACL support in Perl is imperfect, at best, but there is
some support for them. What you needs it the 'filetest' pragma. See the
man page for filetest(3). It may or may not satisfy your needs.
