According to perlre: `\E end case modification (think vi) \Q quote (disable) pattern metacharacters till \E` [download] Depending on what sort of text you want entered in $matchtext, this could be great or a disaster. Assuming that there were a few lines of code between the regex and the initialization,it would be pretty easy to forget that metacharacters are disabled. So if you take this route, make sure to leave a note for yourself where you set the variable. Running the wrong regex to diddle a bunch of files can ruin your day. (How good are your backups?)
