Hi

That's because the [...] creates an anonymous array ref and the %hash is expanded to a list inside.

I'd say this is cargo cult, say "%hash"; should have the exact same effect.

edit

I was wrong, it helps adding white-space through $"

#!/usr/bin/perl
use strict;
use warnings;
use feature 'say';


my %hash = ();
$hash{name} = 'Michelle';
$hash{age}  = 22;
$hash{city} = 'Austin';

say "1: @{[%hash]}";
say "2: %hash";
say "3: ",%hash;
say "4: ", join $",%hash;

1: city Austin name Michelle age 22
2: %hash
3: cityAustinnameMichelleage22
4: city Austin name Michelle age 22

but I'd certainly prefer Data::Dumper or Data::Dump here, or at least say join " ", %hash
