Wouldn't it be semantically saner to use defined? i did mention a common use in split( //, ... ). that explodes a string into an array of all the chars which is useful sometimes. and that is always an null regex afaik. it has the same effect as m/(.)/s in a list context. and defined has nothing to do with m//. m// matches a null string or anywhere between chars. it would work on an undefined value but trigger the usual warning. uri -- Uri Guttman ------ [email protected] -------- http://www.sysarch.com -- ----- Perl Code Review , Architecture, Development, Training, Support ------ --------- Free Perl Training --- http://perlhunter.com/college.html --------- --------- Gourmet Hot Cocoa Mix ---- http://bestfriendscocoa.com --------- _______________________________________________ Boston-pm mailing list [email protected] http://mail.pm.org/mailman/listinfo/boston-pm
