Sorry, a bit more. See also this thread, where Daniel Cid noticed
something similar:

The initial shell was probably run with 'perl foo.pl', so execute
permission wouldn't matter.

jamie@pokey:~/test$ chmod a-x foo.pl
jamie@pokey:~/test$ ls -l foo.pl
-rw-r--r-- 1 jamie jamie 28 2007-06-18 18:11 foo.pl
jamie@pokey:~/test$ perl foo.pl
foo!

cheers,
Jamie
