chas has asked for the wisdom of the Perl Monks concerning the following question:
I'm trying to match strings such as "X \ n a x" which appear
in spam email so I can filter. I can do this but not in a completely satisfactory way. I guess I've just gotten myself confused, but I don't understand why
produces "OK1" only. I would expect the first match to fail and the second to succeed. Thanks for any comments!$_="X "; if(m'X\ '){print "OK1\n";} $_='X\ '; if(m'X\ '){print "OK2\n";}
