( #3333=superdoc: print w/ replies, xml ) Need Help??

However, when you

use strict;

writing

$foo++;

will cause perl to complain (if you have not declared (and thus created) $foo before),
while writing

$bar[396]

will cause no complaints, even if you never used this index before(or a higher one), or never told Perl how big @bar should be. You will have to declare @bar, of course. So these two examples are not comparable. And I believe the second example actually is where we see autovivication at work.
