in thread Perl is not Dynamically Parseable
It's fallacious because you need to know you will reach the code which can make the determination. And to know, in general, that you will reach that nullarity-determining code you've got to know the answer to the Halting Problem in every form it can take. Being able to determine the nullarity of a Perl function, given arbitrary Perl code, amounts to being able to fully predict the operation of a Turing machine.
