Perl is almost always used to create “write once code” and therefore ends up not being taken seriously as a modern web app development language...

For any language in which a reasonably skilled practitioner can distinguish between obfuscated and de-obfuscated code, it's the fault of the programmer if code is unreadable to anyone who actually knows the language.
The readability of a program is meaningless to people who don't know the language. Likely also the problem domain.
It's time to talk about write-only coders instead of write-only languages--at least if you actually care about quality software rather than having a sneering contest.
