The interpretation is only translating into standard Perl one-liners, and by default the execution writes to stdout instead of modifying the file. I haven't written code to actually do the text transformations. My normal workflow is to write commands, pipe them together as needed, and when I think I am satisfied I'll store to a temporary file. If I really need to be extra sure then I will use my preferred ddiff tool to compare against the original before doing the swap. I may have mis-interpreted but I hope between this and the unit tests your concerns are alleviated
