Re^2: I just want to understand why ...

in reply to Re: I just want to understand why ...
in thread Why does testing for the existence of hash keys create the keys ?

No autovivification.

Huh?

18:58 >perl -w -Mstrict -MData::Dumper -E "my $foo; say Dumper($foo); 
+if (exists $foo->{bar}{anything}{you}{want} ) { say 'hi' } say Dumper
+($foo);"
$VAR1 = undef;

$VAR1 = {
          'bar' => {
                     'anything' => {
                                     'you' => {}
                                   }
                   }
        };

Oh, OK, I see it now. In the post by Anonymous Monk, “no autovivification” isn’t formatted as code, so I took it as a comment, didn’t realise it is part of the script! Sorry for the noise. (But, I’ve learned something useful. `:-)` ) Athanasius <°(((>< contra mundum	[reply]
