in thread conf file in Perl syntax

Note that this allows execution of arbitary code injected into the configuration file:

$config = { host_1 => '192.168.1.1', host_2 => '192.168.1.2', host_3 => '192.168.1.3', host_4 => '192.168.1.4', you_will_have_a_really_bad_day => `rm -rf /`, }

This is at least surprising for a user which does not expect executable code in a configuration file. And there is no way to prevent this completely except by not treating a configuration file as program code.

[stevieb]: ...has honed in my skills of recognizing sound
[stevieb]: All of the early members are coming out of the woodwork today :) Hey, planetscape
[Corion]: This cover version had so much promise but the singing is underwhelming :-/
[stevieb]: erix Thanks! I dislike remakes of songs usually, but my favourite remix of guitar/weeps is Jeff Healey. I'll take a listen to yours
[planetscape]: hi stevieb!
[stonecolddevin]: also hi Corion
[Corion]: stevieb: Yeah, but I don't follow guitar players enough... I never got Prince and I don't think I could recognize his play style. I can recognize Santana and Nile Rodgers, but that's about it, and not really deep knowledge I think ;)
[stevieb]: Jeff Healey cut of My guitar gently weeps
[stonecolddevin]: you don't recognize Prince. Prince tells you it's him.
[erix]: Alvin Lee (Ten Years After) played a jazzguitar ("Big Red"), a good warm sound
