I failed to note in my earlier comment that yes, it is so much harder. Fizzbuzz requires that you write a loop, print some strings, and either maintain a couple of counters or use the modulo operator. Your solution requires:
- writing a subroutine
- understanding Perl parameter passing
- understanding Perl regexps, including =~, anchoring, alternatives, metacharacter escaping, character classes, and repeat counts;
- the ternary operator.
And then you could probe things like:
- Do they know how to fix the bug in your version where it incorrectly accepts an IP address with a newline appended to it?
- Do they know it would still work without the return and the ?1:0?
- Can they figure out that they could simplify and clarify the code substantially with qr?
- Do they understand why someone might prefer a non-regexp-based approach? :)
