I'm betting all or most of them? While Catalyst looks awesome (I'm going to be playing around with it in the imminent future for a project I have in mind), it still seems relatively new and a lot of people aren't familiar with it. In the web app arena, PHP, Rails, etc, seem to be the best known and most popular solutions. Perl just isn't considered as a first tier solution for new web apps (although hopefully Catalyst will change that). When you look at non-web app startups, I would expect perl to be much more common. It may not be the focus of the company, and they may not be building a single huge application in it, but I wouldn't be surprised to see it showing up somewhere. I can say that the company I work for isn't too far from being a startup, and while we're currently rewriting a major perl application in Java (because our Dev manager loves all things Java), but even so, new small projects are constantly being done in Perl just because it works so well.

As an example, create a callback on a DBD::Sybase handle for prepare such that if the server type is ASE, leave the sql code alone BUT if the server type is IQ, replace all db..table reference with db.table. The alternative is recoding when moving to an IQ server or building the query with in if/else statement. Can you put callback on connect and disconnect? I'm sure that could be useful for something.

That's why I wanted to dig into it a little to see what merit, if any, there was. They make two big claims: "The TIOBE Programming Community index gives an indication of the popularity of programming languages" and "The ratings are based on the number of skilled engineers world-wide, courses and third party vendors." The first of those I could accept, just, if popularity was in quotes and with a caveat added like "based on the popularity of a simple search term". The second just seems plain wrong. The most charitable explanation is that those are the kinds of things most likely to generate hits, but the statement is certainly misleading.

What does the number of hits for "X programming" have to do with anything? It is absurd for him to draw the conclusion that Perl is less popular as a programming language because there are fewer hits for "perl programming" in any given search engine. It is a leap of logic so huge that I'm astonished that anyone gives a damn. This is all arguing about nothing. What does the number of hits for “X programming” have to do with anything?

I do use unless occasionally, but only when it reads much more naturally than any alternative, and when the conditional expression is trivial. So in this case I certainly broke the second part of my own guidelines, and I probably broke the first as well. When I'm trying to avoid an 'unless' I find myself using 'not' more than '!' these days. So I'd probably write the expression as next if not $x or $x->{as_of_rev} ... You’re right of course Adam.
