I think that newbabymonks is the interviewer not the candidate. My guess is that he is a non technical manager at a company that does outsourced programming projects, and that they have just landed a contract to maintain some legacy perl on the strength of exaggerated promises and a low ball fee.
Except they have no perl programmers on the payroll, so they need to recruit some fast hence their urgent need for some technical questions to filter out applicants that have lied about their qualifications. I doubt it will end well.
