JWK> Perhaps you meant to use the higher precedence operator eq: i think you mean lower precedence. eq lets ref eat its single arg and then compares it to 'HASH'. the comparison ops are generally low binding compared to the math and similar ops (and =~ is just below the math ops in the precedence table). and to the OP, when checking for ref types use eq as a regex is overkill and slower. you know the ref type will be a fixed known string. 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 --------- -- To unsubscribe, e-mail: [email protected] For additional commands, e-mail: [email protected] http://learn.perl.org/
