Dunno, but I can guess. Good sir, you responded quite brilliantly to this post, once again demonstrating your quick and well-seasoned technical skill. Every one of the posts in the thread promptly got up-votes from me as well as (I see) many others. Deservedly so.
So ... where did the “catty comment” come from, and why? The OP has a big requirement, has obviously spent a lot of time already wrestling with it, and just got a helluva genius-boost from (in particular) you. Why the rest of it? What does it add ... why say it at all? You are eminently qualified to speak with authority to “any-and-all edge cases that require large amounts of data to be processed in short amounts of time using Perl.” Why be rude about it?!
