I'm not qualified to comment on the variations among systems or the lack of determinism, but as far as coding defensively, you could just put a filter on the files with grep :

foreach my $file ( grep { !/^\.{1,2}$/ } readdir DIR ) { munge($file); }
perl -e 'print "How sweet does a rose smell? "; chomp ($n = <STDIN>); +$rose = "smells sweet to degree $n"; *other_name = *rose; print "$oth +er_name\n"'
