To use the nice mod_perl debugger you've always wanted:
To connect the two and start up your apache with no fuss:
# httpd.conf
<Perl>
use Enbugger;
# Send the debugger to your waiting terminal server but disable readline
# because I haven't figured that part out yet.
$ENV{PERLDB_OPTS} = 'RemotePort=localhost:53505';
$ENV{PERL_RL} = 0;
Enbugger->load_debugger;
</Perl>
This is all flexible so you can have an ordinary forking mod_perl and don't need to start it any strange way. If you're adventurous, you could inject this right into your running mod_perl by using that snippet somewhere in your application. If you're desperate and have a problem in production and want a debugger there, check out http://bit.ly/bGqCOT to add it at runtime from the outside.
I'm still playing with the proper settings for $ENV{PERL_RL}. I used 'o=0' yesterday and it seemed ok but maybe ought to be 0 instead. Also, I think possibly the terminal servers want more work.
Found on my hard drive. I love that it's source code that's literally in UTF-8 and it all just looks "right" or whatever that Russian says.
use utf8;
use Encode 'encode';
print encode("ascii", 'Я очень рад, ведь я, наконец, возвращаюсь домой', sub{ sprintf "", shift });;

Sometime last year I had to go find out what happens under the covers when a user types a command like "perldoc strict." Here's the trace of which commands call which other commands. It's all in good fun.
I'd used strace to get a process-by-process trace of what happened to just the execve and clone syscalls.
strace -e trace=clone,execve -ff perldoc strict
And the eventual picture resolved:
