[perldigious]: Quick question, is undef %hash a recommended/good way to delete an entire hash structure from memory? Or sould I be doing it some other way?
[1nickt]: The best way is to scope it tightly so it just goes away when you are finished with it.
[perldigious]: but... but... perldigious is the unvirtuous kind of lazy in this case. :-)
[perldigious]: Just kidding. Thanks 1nickt, I'll go ahead and do it the right way. An extra set of brackets and a little extra indentation isn't too much to ask.
[karlgoethebier]: perldigious: perhaps a block if you are paranoid ;-)
