Re: Autovivification Confusion

But shouldn't Perl have interpreted this

my $count{'abc'};
[download]

my %count = ( 'abc' => undef );
[download]

This is how I understand how autovivification works.

Yes, if `my $count{'abc'};` made sense, that could be an expected result. He had `my $count{'abc'} = 0;`, though, which is why he's expecting a different result. This is how I understand how autovivification works. autovivification is the automatic creation of variables when they are needed. No part of the OP's file contains code that uses `%count` (just `$count`), so it's never needed, so autovivification has nothing to do with the OP's problem.	[reply] [d/l] [select]
