A useful framing note: ’s Slashdot pointer sets the tone, and the thread oscillates between ’s hope to stump Larry, ’s jokey suggestions, and ’s tongue-in-cheek Guido idea. For something that remains valuable years later, favor questions that reveal intent, trade-offs, and concrete practices rather than trivia. The list below collects focused, interview-worthy lines of inquiry likely to produce lasting, practical answers.

  • Which single early design decision most shaped Perl’s long-term evolution, and would that choice be repeated today?
  • What were the intended trade-offs behind sigils and context sensitivity, and how should maintainers use those features for clarity?
  • Concrete examples of backward-compatibility decisions in Perl 5: what mechanisms worked, which caused pain, and why?
  • How does the regex engine’s design influence safe patterns today—practical rules to avoid catastrophic backtracking and to write Unicode‑aware regexes?
  • CPAN quality control and dependency management: what policies or tools improved ecosystem health, and what still needs work?
  • Lessons from the long Perl 6 development: governance, specification vs. implementation, and community expectations.
  • Practical advice for modernizing large legacy Perl codebases (testing, automated refactor patterns, and incremental deployment strategies).

Complementary topics that produce human insight: origin and meaning of TMTOWTDI in everyday coding; trade-offs between terseness and readability; memorable debugging anecdotes that illustrate language design choices. Rather than asking purely personal or prank questions (a la ), a lighthearted opener can warm the conversation but should be followed by at least a few questions that produce actionable guidance for people maintaining or learning Perl.

I wonder if anyone could stump him, lol

Boxers or briefs? Wait, to hell with that one! Do you Yahoo? Bah...nevermind!

If you got in a fight with Guido van Rossum (the creator of Python), do you think you'd win?

I'm sure some Perl Mongers and Pythonistas would want to see that...
