Google turned up this comp.lang.perl.misc thread: http://www.dbforums.com/showthread.php?s=6aaf30de92e7732ff45d667075f997bf&t=1071763 which seems to establish pretty conclusively that SvOK() is *the* way to check for defined-ness, and the SVt_NULL test is wrong as well as useless. So barring objections, I'll go make the code do it that way. regards, tom lane ---------------------------(end of broadcast)--------------------------- TIP 1: if posting/reading through Usenet, please send an appropriate subscribe-nomail command to [EMAIL PROTECTED] so that your message can get through to the mailing list cleanly
