Thank you again for this.

 

On the other hand, you are right that the evaluated string may expose some risk especially I'm planning to let other people define this regex string from command parameters.

So, just limit it in the perl program scope, do you have any suggetions how we could easily check through these regex strings to make sure they do no harm?
