Unrecognized escape \Q passed through in regexby Articuno (Beadle) |

Articuno has asked for the wisdom of the Perl Monks concerning the following question:
Hi Monks! Please, I need some enlightment about a regex error... Why am I getting these errors ? I thought \Q and \E where valid escapes for regexen :-( The $regexp is retrieved from a DB, and came from an user (the interface appended \Q...\E before storing it in the DB) The offending code snippet is this: And the "STDERR" output before the error is:
Thanks in Advance :-) Update:Maybe I wasn't clear about a point: the regexes come from a DB, and in DB they already had \b...\b, and now some (few) of them have \b\Q...\E\b there. Is isn't my script that is messing with them... last update:Thanks ikegami-san (who explained the point about \Q...\E in interpolations), and others who helped. I'm accepting more suggestions, but for now, as the regexes are "simple" (whatever that means :-)), I'll go with quotemeta()'ing whatever is inside \Q...\E (the text in question has no "\" so I wont fall in the \\Quux trap :-))
