in reply to C-Style Struct?

To BrowserUK, I ran your code, the output is just 'thing'. I would expect it to print 123. What does that line ( print $thing{ list }[123]) do?

      My self has few answers, that's why I come here. How would I iterate through the array $thing{list}? ie, what would I write for a foreach loop?
        How would I iterate through the array $thing{list}? ie, what would I write for a foreach loop?

        my %thing = ( name => 'fred', count => 100, list => [ 1..10 ] ); print $thing{ list }[ 3 ]; 4 for my $item ( @{ $thing{ list } } ) { print $item; } 1 2 3 4 5 6 7 8 9 10 for( my $index=0; $index < @{ $thing{ list } }; ++$index ) { print "$index : $thing{ list }[ $index ]"; } 0 : 1 1 : 2 2 : 3 3 : 4 4 : 5 5 : 6 6 : 7 7 : 8 8 : 9 9 : 10 print for @{ $thing{ list } }; 1 2 3 4 5 6 7 8 9 10

        With the rise and rise of 'Social' network sites: 'Computers are making people easier to use everyday'
        Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
        "Science is about questioning the status quo. Questioning authority".
        In the absence of evidence, opinion is indistinguishable from prejudice.

        The start of some sanity?
