I wouldn't mind seeing a list of points about why you should do project x in perl instead of php.
I hate php. I love perl. That's just me maybe.
I've figured out reasons why myself in the past but I often explain the same thing to different people lots of times and if there was one place it would be useful. Maybe that one place would get translated into lots of languages, and have a jobs page, etc.. :)
My starter reasons:
Perl is more fun
Java's often not worth it
PHP's a dumbed down version of an old perl
Perl has CPAN (pro-CPAN points below)
you know whatever you need to do can be done (except maybe hard realti
+me embedded but even there..) which is good for when you have growing
+ function sets
growing language esp. with parrot which will take over the world etc.
Perl supports professionals as well as newbies while PHP well anyway.
separation of design and html possible
leverages native code via fast modules in C (or whatever)
automatic building on different platforms
line noise is a figment of your imagination
easy to use sophisticated algorithms
slowness is likewise a figment of your bad coding skills etc.
mod_perl with Apache rocks
dynamic & growing
high general quality level
search.cpan.org usefulness with issue tracking
automatic installation on command line
(maybe not for windows.. vis a vis unreleased ppms)
other advanced languages have started to flatter it by copying idea
less reinventing the wheel
many objects supported between modules
get modules separately which are in later perl versions
wide selection of paradigms for templating, data retrieval, etc.
