Comment 2 for bug 1346553

This behaviour is expected; the 'executable' in this case is the shell script (/tmp/runme.pl in my example, ~/hello.pl in your example) -- and the interpreter is invoked almost as an aside.

We could investigate extending this as a feature request; I don't know if the design of binfmt_misc would make it 'easy' to add permission checks to the interpreter, but we wouldn't want to do it without some level of wider discussion first.

Thanks
