Fellow Monks,

I recently read through Jeffery Goff's excellent Parse::RecDescent tutorial. This inspired me to write my own context free grammar to parse the results of Data::Dumper, as eval-ing the structure is a huge security hole.

I've got everything working except for escaped character interpolation on double-quoted strings (e.g. "\t", "\n"). In other words, I want to be able to convert the string '\t' into ASCII 9. Is there an easy way to do this other than writing regexs for every escape I want to catch? Please note that I do not want to use eval, as this would just reintroduce the security hole. I also do not want to do any kind of variable expansion.

Thanks!

BTW: I realize that Data::Dumper dumps its strings in single quote mode. The interpolation is solely for completeness. :)
