Monks ~

I'm trying (for readability's sake) to assign a branch of a nested hash to a new hash variable. I've solved my problem, but maybe I can decrease my Perl purity and solve it a different way next time. Here's a simplified version of the code:

# main nested hash
my %pages = (
    add_event_type => {
        show => {
            template => "add_evt",
            first_control => 'event_type_name',
            data => {
                event_type_name => { type => 'text', req => 1 },
                event_type_description => { type => 'text' },
            },
        },
    },
);

# elsewhere
my $page = "add_event_type";
my $action = "show";

# the code in question
my %page = %{ $pages{ $page }{ $action }};

# which allows, later
my $first_control = $page{ first_control };

# instead of 
my $first_control_again = $pages{ $page }{ $action }{ first_control };
