$ /lib/ld-linux.so.2 /tmp/anexe
(or in this case)
$ perl /tmp/hi

Those are just two off the top of my head; I've read of enough others
to wonder whether noexec /tmp really buys you much, other than tripping
up virus and trojan-horse writers that haven't considered that case
and planned for it (e.g. `pwd`/.hi instead of /tmp/hi).
