Re: hash assignment wierdness

[DigitalKitty]

Hi Bro. Doug.

As mentioned in the chatterbox by andye++, the Data::Dumper module, while not perfect, is a useful tool.

#!/usr/bin/perl 
use warnings; 
use strict; 
use Data::Dumper; 

my %hash = undef; 
print Dumper \%hash; 

#Output 

$VAR1 = {
          '' => undef
        };

Update: bart++ for suggesting a reference to %hash.

Hope this helps,

The output of Data::Dumper is misleading here, as it looks like undef was assigned to the value, not the key. But it's the key that gets the scalar:

qwurx [shmem] ~ > perl -le '%h = "one"; print "$_ => $h{$_}" for keys 
+%h'
one =>
