  • Data is in an object usually by saving it in the object variable. For example, most people most often use hashrefs as object data structures:

        sub new {
            my $class = shift;
            return bless {}, $class;
        }

    Some people will just allow data access via this hash, directly:

        sub new {
            my $class = shift;
            return bless {blargh => 'data'}, $class;
        }

    • I get everything except {_data}. I've never, never seen that before to the best of my recollection. Looking up {_data} came up blank in _Bookshelf_.

      So that I can look it up, what's that called?

      You are what you think.
      • _foo is a convention for "this is private, don't touch it." So by putting your data in the object hashref under the _data key, you are telling people who use the object and inspect its contents that they shouldn't touch that data directly, but access it via the published API.
