It's not just managers. Far from that. There are many knowledgable people who won't touch Perl with a 10 foot pole. Very good programmers. And they are right, Perl isn't their thing.
It's not just perception. The problems people see with Perl are real. Perl is a handy tool. Multipurpose. But it's also difficult to handle, it's dangerous, and it has a lot of quircks. It's not for everyone. In fact, it's not the right language of many people currently using Perl. If I look at Perlmonks or Usenet, I'd say th

My sense of Advertising is not to run to everybody and say "Perl is the Best, you shouldn't use anything else", but to show what Perl is good for. And that Perl programs can be as "clean" and "maintainable" as programs in other programming languages.

The mistake you are making here is that you assume that it's that problem that makes a language suitable. And while the problem plays some role in picking the right language, the programmer is far more important.

In fact I don't even mind that there should be another language for this kind of thing, I just wish it could be something other than Java or C#. Something more like Ruby.
Can the "why" be fixed with something other than Java/C#?

What I learned writing PPI (Score:1)
Java has a simple structure, it's easy to parse. So the editors and toolchain can be made SO much more rich for Java than for Perl.
Then do extra checks at compile time, that we can't do.
They have the equivalent of strict and warnings on by default.
All of these checks are aimed at weeding out evil as early as possible, and managing it when it happens (exceptions).
Of course you can write evil at the level above where the toolchain ca

And that's perhaps part of the reason why many seem to prefer Java. Yes, it can shackle programmer creativity, but then, it's harder to hang oneself while wearing shackles. If this analogy is valid, then it suggests that it really is safer for some (not all!) companies to pull the average Java programmer off the street instead of the average Perl programmer.

Certainly not, but any perception program ought to be realistic about features of Perl as compared to other languages.
People criticize Perl for allowing people to write quick one-offs, yet that's an explicit design goal of the language! If people can do that productively, maybe Perl's easy to learn, especially for non-programmers. If Perl's easy to learn, maybe finding decent Perl programmers isn't as hard as it seems -- if y

Somehow, I doubt that. I don't have any evidence as to why that would be false, but in my experience, that's not as true as it would seem.
Python, too, was designed to be easy to learn. And it seems that any decent programmer who tries to learn Python does. But Perl seems to evoke a viseral sense of distaste in many capable programmers. Python and Ruby, as languages of a similar vintage, do not engender that reacti

Yeah, but that doesn't say anything. Lines of codes is a non-measurement. It doesn't anything. You might as well argue that NASA is a simple shop as they only have a two vehicles to maintain - much less maintainance than the farm with five wheelbarrows.
A single complex line of code can be much harder to debug (and maintain) than five simple ones.

That's a very negative way of looking at the problem.
One thing managers are used working with that we aren't so much is the element of Trust as a malleable entity.
When you work alone, or in small teams, you can learn a lot about people, and trust isn't a big issue.

Not at all. It's the engineer's lament that the best solution frequently doesn't win. This is just a case where superior technology (e.g. Perl) is loses out to an inferior technology (e.g. Java).
