Hi Monks, I would like to implement a system where users can enter code in a configuration file (in the form of if/else) with a single parameter (like $_). Something like that 
if($_ > 10){return 1}
elsif($_>3){return 2 } 
else {return 1 }

Then this code should be called when needed and maybe 'eval'ed as a sub reference. I'm not totally satisfied by this solution however, first because of security problems, I don't want my user to possibly launch system programs (ok, they won't, but they could..) second because I think eval could take some time and slow down my system. What do you think? I'm seeking your wisdom.
