From my point of view, I'd like to re-iterate what I discussed with
Dave Cross and Ovid on thursday in the pub.
I can't use a programmer who's just learnt how to hack together a CGI
script, but this Person probably has all the skills I actually need
in writing Perl. It's the stuff around it that's the problem.
They've generally got the syntax down, or if they spent a while
reading the camel, they would have.
The stuff they need to know is the other stuff, the stuff that they

* How to write POD, and what's expected in standard POD like you'd
find on CPAN.
* How to make a very simple module tarball
* How to debug (note, this isn't how to use the debugger, but more
Hey, Data::Dumper exists, perl -c exists, Devel::Peek exists)
* How to find out what your dependancies are
* How OO concepts is represented in Perl. This is mainly an exercise
in teaching the language. (What's an "accessor"? What's a "class
method"? What's an "object method"? What's a "package variable"?)
* The very basics of character encoding in Perl
* How not to trust user input (escaping output to the browser, to the

Module::Build, mod_perl, FastCGI

is about turning a CGI script author into someone who can do "proper
