Tom Lane asked: > Please, tell me that isn't so. $a is a reserved name now? What was > Larry thinking? It's not that bad, really. $a and $b have special meaning inside of a sort subroutine as the two items being compared. Thus, you can write something like this: my @crooks = sort { lc $a cmp lc $b } @whitehouse; to create a list sorted by lowercase (albeit not in the most efficient matter). This will work even with "use strict" turned on, as $a and $b will not trip Perl's strict-mode checking of undeclared variables. So, the danger is very minor, but it's a good practice to not use them for temporary variables in a script. - -- Greg Sabino Mullane [EMAIL PROTECTED] PGP Key: 0x14964AC8 200510182220 http://biglumber.com/x/web?pk=2529DF6AB8F79407E94445B4BC9B906714964AC8 -----BEGIN PGP SIGNATURE----- iD8DBQFDVa2qvJuQZxSWSsgRAoMSAJ4i+TlQOYUw5w8VCLqsSKakfgaWfQCfeqGo n5Rn3XwUZZgwdHrs/7i3GNI= =/0mE -----END PGP SIGNATURE----- ---------------------------(end of broadcast)--------------------------- TIP 4: Have you searched our list archives? http://archives.postgresql.org
