in reply to A "simple" question regarding accessing a value in a complex data structure.
The odd number of hash elements warnings arises from the fact that there is only one key? Thanks
Yes, a key without a value, specifically { q/Expert's Guide to Scala/ },
my $hashref = { 'hasherefs', 'are', 'made', 'with', 'curly', 'braces', 'they', 'like', 'to', 'come', 'in', 'pairs' };
Here is another way to initialize , the rehohy way
my %tgs; $tgs{articles}{Python}{Programming}{"Expert's Guide to Scala"} = undef; #d3 $tgs{articles}{Perl} = "Perl Programming for Biologists"; #d1 $tgs{articles}{Java} = "How to Program in Java"; #d1 $tgs{eBooks}{Linux} = "Linux: A Beginner's Guide"; #d1
And wouldn't you know it, its also a way to access certain elements :)
